Apache2 crash

Postby miroslawwos » 02 Aug 2017, 19:32

We use Stalker v5.1.1, Apache/2.4.7 (Ubuntu),PHP 5.5.9-1ubuntu4.21, Zend Engine v2.5.0,Linux stalker 3.13.0-32-generic.
Middleware works with 300 MAG254 stb connected.
Last week the system started to crash.
There are two problems seen on the subscriber's side:
-Loading portal stops in half (restart stb required)
-No channels on the channel list (restart stb required)
Log from nginx:
2017/08/02 21:15:31 [error] 21214#0: *87894 upstream prematurely closed connection while reading response header from upstream, client:, server: localhost, request: "GET /stalker_portal/server/load.php?type=itv&action=get_all_fav_channels&fav=1&force_ch_link_check=&JsHttpRequest=1-xml HTTP/1.1", upstream: " ... uest=1-xml", host: "", referrer: ""

Log from apache2:
error.log:[Wed Aug 02 21:15:32.053204 2017] [core:notice] [pid 17928] AH00051: child pid 22905 exit signal Segmentation fault (11), possible coredump in /etc/apache2

Result from apache2 coredump:
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `/usr/sbin/apache2 -k start'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x00007fb16f02f511 in zend_std_write_property () from /usr/lib/apache2/modules/libphp5.so

Can you help me solve the problem?
