SSL_write() failed (SSL: error:1409F07F

Hi

nginx используется в качествве фронтенда, Имеются проблемы с отдачей некоторых
страниц, например некоторые файлы оказываются недокачанными. В логе такое:

2008/10/15 17:13:11 [crit] 3352#0: *906298 SSL_write() failed (SSL: 
error:1409F07F:SSL routines:SSL3_WRITE_PENDI
NG:bad write retry) while sending to client, client: 77.242.xx.xx, server: 
xxe.xx.ru, request: "GET /s
tudent/TestList.aspx?sem=2 HTTP/1.0", upstream: 
"http://xx.xx.x.xx:80/student/TestList.aspx?sem=2";, host: "xx
xx.xx.ru", referrer: "https://xx.xx.ru/student/TestStudent.aspx";

Гугленье показало что подобные ошибки наблюдались в nginx 0.5.35, в ветке 0.6
было исправлено. Но тем не менее я ловлю это на 0.6.31. 

Если включить дебаг, видно такое:

конфиг:

        }
    }

В чём может быть причина? Чего делать?
