Hi,

I have one setup (nginx 1.2.8 and push module 0.3.5) and seems that is affected by

https://github.com/wandenberg/nginx-push-stream-module/issues/154
https://github.com/wandenberg/nginx-push-stream-module/issues/100

due I see following in the logs
nginx-push[21756]: segfault at 0 ip 0000000000497c06 sp 00007fff91619360 error 6 in nginx-push[400000+c8000]
nginx-push[6306]: segfault at 0 ip 0000000000497c06 sp 00007fff91619300 error 6 in nginx-push[400000+c8000]

nginx-push[25129]: segfault at 44c1c4 ip 000000000049d54d sp 00007fff916193d0 error 7 in nginx-push[400000+c8000]
nginx-push[2664]: segfault at 0 ip 0000000000497c06 sp 00007fff91619360 error 6 in nginx-push[400000+c8000]

My question is if there are some known cause of the issues (and possibly know-how to reproduce those) mentioned above so I can try out of production site before going into full debug?

Thank you in advance and best regards

Hi,

Those problems are hard to reproduce locally, they depended of the load, concurrency and if the client closes the connection at some specific moments.

I suggest you to move to the latest release of the module, update one of your servers and compare to the old ones.

Regards,
Wandenberg
