-
@greg-plamondon OK let me update my dev box (its still on 1.5.0) to see if I can find anything.

proxy_fcgi
That kind of tells me that php-fpm was enabled and its having an issue. What OS do you have Greg? My dev box is centos so I should be able to duplicate Troye’s issue.
I wasn’t aware that the devs enabled php-fpm (which is generally a good thing to have running).
-
@george1421 I am running Centos 7.4 x64
-
(still waiting for my dev server to update)
I did do some testing for php-fpm a while ago: https://forums.fogproject.org/topic/10717/can-php-fpm-make-fog-web-gui-fastThe idea of php-fpm is a dedicated php engine that executes much faster than the built in php engine in apache.
-
@george1421 ok not related to php-fpm.
How many client computers do you guys have on your campus?
-
I have about 130-150 clients.

Did you purposely put
10fogserver
in there? -
@george1421 OK I’m back hunting php-fpm timeout.
For those with the error can you review this log file to see if it gives us any clue to why
/var/log/php-fpm/www-error.log
-
@george1421
I followed your FPM/FastCGI howto you linked and the problem seems to be gone and considerably faster now.
Thanks! -
I will try your guide.
-
@wayne-workman Yes, as we have more than one.

Its great we have php-fpm running, it does make quite a difference, but we need to understand why. I can’t seem to make it fail on my side, but I only have a handful of systems on my dev box.

@greg-plamondon Ok it looks like an upper memory limit got us. OK lets see what we need to do to fix. @Troye-Johnson since Greg already tainted his system hold off for a minute updating yours so we can see if we can fix this memory issue.

@george1421 change the memory limit it fogsettings
