@george1421 So I am pretty sure it is fixed now. I looked at the logs for php and found this error

[20-Aug-2019 17:28:19] WARNING: [pool www] server reached pm.max_children setting (5), consider raising it

So I changed the pm.max_children setting to 150, just to be sure, and it is now working perfectly!
I re-imaged the same lab with 20 computers and monitored the server to see how many php-fpm services ran and I found that at one point I had 10 instances so bringing that up from 5 did help for sure.

@Sebastian-Roth I restarted the service and the server too just to be sure.

@george1421 I checked the logs and I think I found the issue. I’m not at my office anymore so I’ll test it tomorrow and update the thread.
Thank you so much for your support, quick response, and excellent help!!

@george1421 Made the changes on the server and deployed the image to a lab of 20 computers and it’s giving me the same issue.

@george1421 Thank you so much! I just did that and will test it by imaging more labs. If anything I keep having this issue today or tomorrow I will update the thread.

@george1421 I found it in /etc/php/7.1/fpm/pool.d

@george1421 Thank you! The php_admin_value line is actually commented out (I don’t know why). Does this mean some other setting could be active somewhere else?

Also, what about adding more than 256M to that value?

@george1421 I can’t access the web interface at all, it gives me either a 503 error or 504. The FOG server works fine for day-to-day imaging, but this happens when I am trying to image multiple labs at a time.

I ran the command that you put in your comment and this is the result

Hello everyone.
I’m having an issue that I have no idea how to solve. I am capturing an image and deploying a different image to 20 computers. Once the upload finished it gave me an error when trying to update the database

I am not able to get into the web interface, It gives me a 503 Error

I am able to SSH into the server though!
I know that I can just restart the server but this is not the first time this happens so I would like to fix it for good.

FOG Version: 1.5.4
Server has 4TB storage and 32GB RAM (don’t think this is the issue but in case someone asks)

Any help is extremely appreciated! Thanks!

!!Update: It now gives me a 504 Gateway error (bottom of screen)
