Добый день.
В этой теме http://forum.nginx.org/read.php?21,231434 выяснили, что core
dump может возникать из-за некорректного использования if и set
nginx обновлён:
nginx version: nginx/1.2.4
TLS SNI support enabled

Поправил конфиги, core dump'ов стало меньше, но появляются следующе
сообщения:
По top'у видно, что память отъедает nginx
