nginx - workers segfaulting

December 02, 2013 01:15PM
Dear All,

I'm facing a small problem with NGINX; The workers are segfaulting since 11:20 this morning. From kernel messages I got soemthing like this:

nginx[6888]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6886]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6890]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6889]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6892]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6893]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6894]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6891]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]
nginx[6896]: segfault at 8 ip 0000000000426a30 sp 00007fff85c01e70 error 4 in nginx[400000+a8000]

The log files show the following:

2013/12/02 18:13:53 [alert] 26876#0: worker process 30412 exited on signal 11

I can provide some cores, but I can't attach them here. My setup was running fine till today (which has some coincidence with a new webservice deployed).

Please could you provide some extra information on how to further debug this issue ?
