cPanel link from List Accounts page returning 503 'The server is too busy to handle your request'
We have a client who is reporting that when they click on the cPanel icon in an account on the List Accounts page on their server they get the attached page. The error logs before the 503 error look like the below. Restarting cpservd appears to fix the error temporarily. There don't seem to be any other issue in the error log.

HI Can you please your disk space usage and see if there any space available on DIsk?.You can check check disk space by using following command df -h Regards 0 -
Disk is fine. Filesystem Size Used Avail Use% Mounted on devtmpfs 126G 0 126G 0% /dev tmpfs 126G 12M 126G 1% /dev/shm tmpfs 126G 4.1G 122G 4% /run tmpfs 126G 0 126G 0% /sys/fs/cgroup /dev/md2 1.8T 980G 691G 59% / /dev/nvme0n1p1 510M 3.7M 507M 1% /boot/efi /dev/loop0 3.9G 99M 3.6G 3% /tmp tmpfs 26G 0 26G 0% /run/user/0 The error there is coming from the cPanel quota monitoring script, which makes me think it probably isn't the issue as it seems unlikely that it would cause something as mature as cPanel to trip over.

Whenever this has happened in the past, it's always been tricky to troubleshoot after the fact. *If* you can get into the server quickly, can you try these commands to see if there are a lot of cPanel processes running? ps fauxwww | grep -c whostmgr[d] ps fauxwww | grep -c cpsrv[d]
The output from either command will just be a number, and typically I'd expect it to be a low number less than 10.0 -
Good tip, we're just seeing it when the client reports it at the moment. Restarting cpservd seems to fix it for that matter and now I'm wondering if it coincides with update processes on the server.

It's completely possible that error happens briefly during an update. 0 -
Hi, check ps fauxww | grep -c webmaild and at "Tweak Settings" you can increase "Max cPanel/WHM/Webmail service handlers". Best regards, 0
