If you neeed more information i can help you

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]

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

[wandenberg]

Hi, can you check if this happens with the new version 0.4.0 3d3a204 ?

[kamil-michalak]

Hi Wandenberg,

No. but I'll try and let you know
