nginx reload sometimes not working(worker processes still alive)

April 15, 2015 09:31AM
hi
i'm not sure if this is an nginx or pagespeed or maybe linux problem

we're using nginx on RedHat
Linux 2.6.32-504.8.1.el6.x86_64 #1 SMP Fri Dec 19 12:09:25 EST 2014 x86_64 x86_64 x86_64 GNU/Linux

nginx1.6.2 with pagespeed 1.9.32.3beta:
nginx version: nginx/1.6.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
TLS SNI support enabled
configure arguments: --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_ssl_module --with-http_stub_status_module --with-http_geoip_module --http-client-body-temp-path=/var/cache/nginx/client_body_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_tempmake --add-module=/tmp/nginx-1.6.2/ngx_pagespeed-1.9.32.3-beta

our problem is, since we have added the new pagespeed version, our reload wont work properly.
we're using the following command to reload our nginx.

"nginx -s reload"

sometimes it happens that the master process is killed, but the worker process of the old master process are still running.
So we are not able to start a new master process while the old workers are still there.
We have no idea why this happens.

the message log file shows the following error:
Apr 15 11:20:51 kernel: nginx[11423]: segfault at 7 ip 000000000047bbe3 sp 00007fffdd7740f0 error 4 in nginx[400000+957000]
Apr 15 11:20:51 init: nginx main process (11423) killed by SEGV signal
Apr 15 11:20:51 init: nginx main process ended, respawning
Apr 15 11:20:55 init: nginx main process (6642) terminated with status 1
Apr 15 11:20:55 init: nginx main process ended, respawning

i have also make/installed pagespeed and nginx again, but no solution for that.

does anybody has that problem? or has an idea what i to do?

Regards Steven
