If you neeed more information i can help you

wandenberg commented 11 years ago

Do you have a core dump? If yes, send it to me, and you nginx executable too.

What is the exact version of push stream module you are using?

kamil-michalak commented 11 years ago

First, I set limit for core dump to low (512MB). Now i changed it to 3GB and still waiting (12-24 hours to next segfault). I use dotdeb package (1.4.2) on debian wheezy 64bit http://packages.dotdeb.org/dists/wheezy/nginx/source/ it's contains Version 0.3.5
