Sophos Connect Charon Logs
I've come across an incident where the Charon logs for Sophos connect reached over 91GB in size, it would have got larger but it had consumed all of the available space on the hard drive. As such, I was unable to download the Sophos help tool in order to seek help and had to use another machine and remotely connect using RDP.
On rebooting, the logs were completely cleared and all went back to normal.
There really should be a process in place that prevents a log reaching that sort of size, maybe log rotation with a purge in place for logs older than x days?
A case was raised with proof of the issue.
