mod_fcgid communication error signal 11 - shopware related

Hi there,

in our company we use an ubuntu based i-mscp server for development purpose.

System:
ubuntu 15.04 (i know...no lts version)
i-mscp 1.2.9 (update planned)
6GB Ram, 3 Cores
php-switcher installed
Apache 2.4.16

In 2 of 5 shopware instances we get an error at the backend (plugin manager) - "i-MSCP internet - Multi Server Control Panel - Error 500 Error 500! Internal Server Error Back" (in a shopware field), a look at the log files shows:

[Mon Jan 11 15:34:22.978913 2016] [fcgid:error] [pid 9348:tid 140168759838592] mod_fcgid: process /var/www/fcgi/xxxxxx/php-fcgi-starter(9410) exit(communication error), get unexpected signal 11

and related:

End of script output before headers: shopware.php

I´ve tried it with PHP Version 5.5.30, 5.6.4, 5.6.8, with and without ioncube, apc disabled...no success. Any ideas?

Thanks in advance
Simon

Hi Nuxwin,

thanks for your reply.

The installed extensions are:

apc
xdebug
ioncube
opcache

the rest is standard.

I disabled apc and now opcache, no changes

Hi Nuxwin,

I disabled at the corresponding php.ini (/var/www/fcgi/xxxx/php5/php.ini)

Opcache:

opcache.enable=0

and I commented the sections with xdebug and apc, so that it wont be enabled. Ioncube has to stay enabled, otherwise shopware won´t work.

Quote from Nuxwin

I could maybe check at your server directly

Yeah would be an option, but tomorrow, sorry

Thanks Nuxwin,

any time-related wishes? How should I contact you?

Regards
Simon

Hi Nuxwin,

after trying a bit more I found out, that the shopware version was kinda incompatible with any PHP Version > 5.3. So I used the PHPSwitcher (btw. great work ) and changed to 5.3.xx - the error seems resolved. Another thing is, that shopware still says "no-encoder", but thats not your problem

Thanks a lot
