Sometimes Sophos releases updates or patterns that corrupts a function in the UTM and make that function crash! – Everytime a core dump is generated, and that is filling up the data disk.
If that happens you eventualle see a notification land in your mailbox saying:
Data Disk is filling up – please check. Current usage: 82%
When logging into webadmin, you may see this:
Clearly the data disk is getting full!
To fix this, you can connect to your UTM’s shell with SSH
GO into the folder /var/storage/cores and issue a “ll” command:
As you can see here, there are a lot of dumps in this case, especially the httpproxy files are huge.
If you do not need to examine the log files, you can safely delete them with the command:
“rm *” for the httpproxy files only issue: “rm httpproxy.*”
After that, all is cleared up and the webadmin will update the storage status in a few minutes:
Hope this helps 🙂
