High CPU, PHP Errors after update to trunk (github) 7234
-
I probably should have posted this in the bug reports section. Please move it if we need to do that.
Updated to 7238, and then 7240 today. Nagios started complaining about sustained high CPU load, and there are several pages that aren’t working.
Here is some info from top:

We’ve seen this before. I think your MySQL connections hit the maximum, and you need to raise it. Look at this:

It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

@apathetic_admin How many clients do you have??
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

@Sebastian-Roth 650ish.

@Wayne-Workman I made that change, unfortunately it does not seem to have made an impact.
I also just tried to run a report and got this gem:

Then let’s try increasing PHP’s memory limit: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_Web_Interface

Spent some time with Tom and I think it’s better now. We rolled back and fourth through various revisions, and then went to php 7, and the load averages are a bit lower than they were before. The report issue was fixed by upping the memory limit for FOG in the FOG settings.

@apathetic_admin May I ask if you still know which version you used before the update? Maybe see the install logs?? You didn’t have any load problems before the upgrade?
