Nginx segfault error that leads to server crash

We have a web server hosting by Nginx, the version of Nginx is 1.12.0 stable version. However, after some time(one hour or several hours) with about 150+ http/https requests, Nginx server will be crashed with the follwoing error in /var/log/messages

May 21 19:44:21 lxci kernel: [191384.313252] nginx[25194]: segfault at 8 ip 000000000041d733 sp 00007fff7f4a43a8 error 4 in nginx[400000+b6000]

in /var/log/nginx/error.log, it has the error message like:

2017/05/21 19:59:21 [alert] 5583#0: worker process 25292 exited on signal 11
2017/05/21 19:59:21 [alert] 5583#0: shared memory zone "SSL" was locked by 25292

After this error happens, no web page can be accessed. Nginx server will refuse to response.

This error happens randomly. This issue also happens in Nginx version 1.11.10 and 1.11.13.(We have tested this two versions, but not sure 1.11.11 and 1.11.12 since we have not test every version. However, since 1.11.13 has the issue we think it may also happen in 1.11.11 and 1.11.12.) This issue blocks our development so we report it to seek for your solution/suggestions.

Any advice will be very appreciated and if you need other required information please kindly post your instructions here. Thanks in advance!

The configure arguments provided in nginx -V output show that you use some patched version of nginx sources. The combination of --crossbuild=Linux:x86_64 and --with-endian=big looks suspicious.

Resolution: invalid
Status: newclosed

Unsupported combination of modified nginx sources and meaningless options.

After change the compile options to --crossbuild=Linux:x86_64 and --with-endian=little , the problem solved. Thanks very much!
