[X2Go-User] x2go server on debian: readonly partition

I am running x2go server on debian testing and connecting to it from another linux machine. Everything works fine but occasionally (approximately after 2-3 days of use over which I connect and disconnect from the client many times), the host machine says the /tmp/... is on a read-only partition, and everything stops working. x2go client does not connect when this happens. I can ssh to the server but nothing works on it. I am unable to even cleanly reboot the machine when that happens. I only need to physically hard-boot the machine.

I don't know if this is happening because of x2go, but it never happened before I started dabbling with x2go.

Is this a known problem? Any ideas about how to debug?
