Issue Apache memory usage keeps growing

[svh1985]

Hi,

Over the last few weeks I noticed that the memory usage of Apache kept growing and I'm having troubles finding the cause.

Config VPS:
CPU Westmere E56xx/L56xx/X56xx (Nehalem-C) (2 core(s))
Version Plesk Onyx v17.5.3_build1705170317.16 os_CentOS 7
OS CentOS Linux 7.2.1511 (Core)
3.70 GB Memory

Sites:
-16 Wordpress sites running on FPM Nginx PHP (proxy mode disabled)
-15 running on PHP 7.2.0 FPM and 1 runs on 5.6.32 FPM
-PHP memory_limit 128M

Server health:


Because the server health is lacking the details to a subscription level. How can I pinpoint what the cause is of the high memory usage?

Thanks!

Which microupdate version are you running? It should say on the homepage when you login or if you issue the command

plesk version

It could be this: After the installation of micro-update 32 on Plesk Onyx 17.5, server memory usage has significantly increased

I'm at Plesk Onyx Version 17.5.3 Update #34, last updated on Dec 15, 2017 03:39 AM
After I set the PHP-FPM pm value to ondemand, the issue was fixed!

Thanks!!
