nginx reload sometimes not working(worker processes still alive)

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
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/
--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

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

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

Regards Steven
