I set up a server following the tutorial on: https://docs.litespeedtech.com/cloud/images/wordpress
I regularly get a 503 error; when I check the logs I see the following:
ERROR [lsphp]: Failed to listen socket [/tmp/lshttpd/lsphp.sock]: No space left on device
WARN [uds://tmp/lshttpd/lsphp.sock] Can not start this external application.
However, there is plenty of space left when I check:
Filesystem Size Used Avail Use% Mounted on
udev 2.0G 0 2.0G 0% /dev
tmpfs 395M 628K 394M 1% /run
/dev/vda1 78G 6.7G 71G 9% /
tmpfs 2.0G 1.2M 2.0G 1% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
/dev/vda15 105M 3.6M 101M 4% /boot/efi
/dev/loop0 1.5G 25M 1.3G 2% /tmp
tmpfs 395M 0 395M 0% /run/user/0
Also, the image should have set the following limits:
Max SSL Connections 5000 10000
lsphp Max Connections 35 100
PHP_LSAPI_CHILDREN 35 100
However my limit are this:
max ssl connections 1000 (not even the 5000 as it should been standard?)
lsphp Max Connections 35
PHP_LSAPI_CHILDREN=35
How come the image didn’t set those and can I just change them via the webadmin console?
Thanks.

Hi there @m86,
It sounds like that your inodes might be full. To check that run the following command:
This usually happens when there is a huge number of small files, that way you have enough disk space but no available inodes, so you would still not be able to add any new files.
If this is the case you need to find the directory which is those files are being created at and delete them.
More often than not this is caused by temporary session files created by your application and then not being removed.
If you are not able to find the directory in question, try running this command here:
Note that it might take a while.
Let me know how it goes! Regards, Bobby
I was able to “fix” this, by upping the numbers manually in openlitespeed:
Max SSL Connections 10000 lsphp Max Connections 100 PHP_LSAPI_CHILDREN 100
Hey. Could not solve the problem? I have exactly the same problem, the server often crashes …
After a reboot, after a couple of days of work, the server again crashes and the error logs:
df -i and sudo ipcs -a have similar values, inodes use 1% and ipcs is empty…
