Ywat Posted May 1, 2017 Share Posted May 1, 2017 Hi everyone, Since the last few days several POST requests to my 2 IPS installations on Apache + PHP 7.1 hang and take up lots of memory (400mb per process). These processes run infinitely in 'Sending reply' mode according to Apache. It even ignores the PHP max_execution timeout. All these hangs occur when posting a new topic or when posting in a topic. And the script 'system/3rd_party/HTMLPurifier/HTMLPurifier/ChildDef/List.php' seems to be related, according to the open files information of the processes. The IP adresses which do these requests are from legitimate users. I know this still sounds vague, but I have no idea what else to say about this. Is anyone familiar with such an issue? Thanks in advance. Link to comment Share on other sites More sharing options...
ASTRAPI Posted May 1, 2017 Share Posted May 1, 2017 You may hit a bug related to IPB 4 and php7.1 using Zend opcache....... Try to disable zend opcache and check again.... That issue is solved on the new IPB 4.2 and it was related to a third part library..... Link to comment Share on other sites More sharing options...
ABGenc Posted May 2, 2017 Share Posted May 2, 2017 I do seem to have a very similar problem . Some of httpd processes hit the CPU up to %90s and do not end for a long time causing the load to rise to 5-10s on a 2 CPU server. How can we look into the process on what it is doing ? I am using opcache too by the way. Link to comment Share on other sites More sharing options...

Listen to @ASTRAPI Disable your opcache, I spent like 4 days with support on this. That is what they narrowed it down to. You will need to leave it disabled until 4.2.

Ywat Posted May 14, 2017 Author Share Posted May 14, 2017 Can confirm disabling opcache in PHP settings/config fixes the issue for now. Thanks! Link to comment Share on other sites More sharing options...
