Cloudron Forum

@girish Looks like that fixed it. No more loading issues, and no more log errors. Thanks!

@nebulon

I'm assuming the php in Kimai is not reading or is overriding the /app/data/php.ini file, from the reply I got from the Kimai dev, and with further testing that didn't change the value in the error messages.

Would you know where the php memory limit is being set to 64M, if that's the case? Could Cloudron be messing with that value?

@nebulon

Kimai has a 2 GB memory limit currently.

I added that line to the php.ini in Kimai, and rebooted Kimai from the Cloudron panel. I then did the same again with 256M. I got the same error each time:

Is it saying php only has 67108864 bytes available? If so, Am I missing a step in getting it to read the php.ini?

Confirmed, here is the link to the post on Kimai's github: https://github.com/kevinpapst/kimai2/discussions/3059

I have increased the memory limit since then, but it has not seemed to help. I'll post the Kimai prod.log entries here as well, in case it helps:

EDIT: Is it possible that I need to increase the memory limit of one of the services, instead of Kimai?

One of our users is not able to access the "Weekly working hours" page intermittently. If they hit the refresh button a few times, it usually loads after two or three tries. This only affects the one user. I'm thinking it may have something to do with a large amount of project listings on their "Weekly working hours" page, but I'm not sure.
The var/log/prod.log is empty, and I don't see anything in the Cloudron log either.
