Проблема с загрузкой и обр аботкой файлов

["copycat" <nginx-forum@xxxxxxxx>]

Добрый день.

Установлена связка nginx/0.8.53 и php-fpm в
поставке с php 5.3.3.
Все работает хорошо, за исключением
одного момента.

С административной панели одного их
сайтов загружаются графические файлы,
загрузка происходит при помощи флеш
приложения Uplodify, который передает
файлы php скрипту.

1. php получает файл, проверяем по $_FILES
2. функцией imagecopyresampled() кропим 3 раза под
разные размеры и сохраняем файлы
3. пишем в базу

Так вот файлы маленьких размеров
порядка 200-300 К грузятся и
обрабатываются без проблем, файлы
больших размеров 3-9 Мб, грузятся не
всегда, из 5 загружаемых файлов успешно
обрабатываются может 2, может 3, могут
вообще никто. Ранее была связка nginx+apache,
то есть php обрабатывал apache в режиме suexec,
и никаких проблем не было, время
конвертирования изображения
состовляло не более 30 сек. Щас же более
3-х минут. И не всегда понятно почему
одно изображение проходит а некоторе
нет, вероятно это связано с размером
файла, чем больше файл тем больше
времени нужно на обработку. Но
показатели 30 сек. против 3 минут это
порядок в 10 раз.

В логах Nginx я вижу следующее:

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different
listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools
which
; FPM can handle. Your system will tell you anyway :)

; Start a new pool named 'www'.
[domain.domain.ru]

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific
address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000

listen = /home/domain/domain.domain.ru.php.sock

; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1

; List of ipv4 addresses of FastCGI clients which are allowed to
connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the
original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each
address
; must be separated by a comma. If this value is left blank, connections
will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web
server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0666
listen.owner = arriva
listen.group = apache
listen.mode = 0666

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default
user's group
;       will be used.
user = arriva
group = arriva

; Choose how the process manager will control the number of child
processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on
the
;             following directives:
;             pm.max_children      - the maximum number of children that
can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on
startup.
;             pm.min_spare_servers - the minimum number of children in
'idle'
;                                    state (waiting to process). If the
number
;                                    of 'idle' processes is less than
this
;                                    number then some children will be
created.
;             pm.max_spare_servers - the maximum number of children in
'idle'
;                                    state (waiting to process). If the
number
;                                    of 'idle' processes is greater than
this
;                                    number then some children will be
killed.
; Note: This value is mandatory.
;pm = dynamic

pm = dynamic

; The number of child processes to be created when pm is set to 'static'
and the
; maximum number of child processes to be created when pm is set to
'dynamic'.
; This value sets the limit on the number of simultaneous requests that
will be
; served. Equivalent to the ApacheMaxClients directive with
mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the
original PHP
; CGI.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 128

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers -
min_spare_servers) / 2
pm.start_servers = 20

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 30

; The number of requests each child process should execute before
respawning.
; This can be useful to work around memory leaks in 3rd party libraries.
For
; endless request processing specify '0'. Equivalent to
PHP_FCGI_MAX_REQUESTS.
; Default Value: 0

pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI
will be
; recognized as a status page. By default, the status page shows the
following
; information:
;   accepted conn    - the number of request accepted by the pool;
;   pool             - the name of the pool;
;   process manager  - static or dynamic;
;   idle processes   - the number of idle processes;
;   active processes - the number of active processes;
;   total processes  - the number of idle + active processes.
; The values of 'idle processes', 'active processes' and 'total
processes' are
; updated each second. The value of 'accepted conn' is updated in real
time.
; Example output:
;   accepted conn:   12073
;   pool:             www
;   process manager:  static
;   idle processes:   35
;   active processes: 65
;   total processes:  100
; By default the status page output is formatted as text/plain. Passing
either
; 'html' or 'json' as a query string will return the corresponding
output
; syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php
extension or it
;       may conflict with a real PHP file.
; Default Value: not set
pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not
set, no
; URI will be recognized as a ping page. This could be used to test from
outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load
balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php
extension or it
;       may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping

; This directive may be used to customize the response of a ping
request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong

; The timeout for serving a single request after which the worker
process will
; be killed. This option should be used when the 'max_execution_time'
ini option
; does not stop script execution for some reason. A value of '0' means
'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0

;request_terminate_timeout = 0

request_terminate_timeout = 240s

; The timeout for serving a single request after which a PHP backtrace
will be

;request_slowlog_timeout = 0

; The log file for slow requests
; Default Value: /var/log/php-fpm.log.slow

; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value

rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as
an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used
whenever
