Uhm... "stuck" is pretty ambiguous in that context - I assume that you are
referring to the CPU usage, which doesn't go down to sane levels even after
reconnecting, but reconnecting to the session as such is possible?

Is there any reasonable way to trigger this behavior? Like starting a MATE
session, disconnecting and waiting for an hour to see the CPU usage spike? Or is
it triggered by other programs running inside of the session?

I'll need something to reproduce it, server OS information would also be great.
Oh, maybe some details

It just happened a second time.
I seem to be able to repro this fairly well.

I am, BTW, not able to reconnect. It just connects and disconnects again.

Is there a way to downgrade?

My setup is rather unusable. If i leave it unattended for 10-20 minutes i have to shoot it down

This is the 4th time today.
