503 errors with PHP and Wordpress

[WiLLL]

Hi,

I am seeing a few 503 errors in a wordpress based site hosted on our litespeed server.

The errors occur on the same pages, mainly when editing certain stories in the backend.

I enabled coredumps, and checked with gdb. This is the output:

Program terminated with signal SIGSEGV, Segmentation fault.
#0 0x000000000077d335 in _zend_mm_alloc_int (heap=0x1e56200, size=79) at /usr/local/lsws/phpbuild/php-5.6.7/Zend/zend_alloc.c:1910
1910 /usr/local/lsws/phpbuild/php-5.6.7/Zend/zend_alloc.c: Ingen slik fil eller filkatalog.

I am running php with suexec with options "Autostart = yes" and "Run on startup = Yes".

Does this mean that PHP cant read that file? I tried "sudo cat /usr/local/lsws/phpbuild/php-5.6.7/Zend/zend_alloc.c" and it printed out a file.

Kind regards,
Wilhelm

general guide for 503 error:
https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:php:503-errors

in your case, if ZendGuardLoader, Suhosin is enabled, try to disable them(if feasible), and see if any improvement.

Thanks for the reply.

I disabled all plugins one by one. The 503 errors dissappeared after disabling the wpml plugin.

I will investigate further with the plugin.l

Kind regards,
Wilhelm
