High CPU load

RT Users
1

Hiya,

I’m seeing some weird behavior on the new RT server.

For some reason the mason_handler.f process is constantly taking up
around 99% CPU load, without 1 user active.

If I give the http server a reboot, the CPU load drops again to 0. If I
do a couple of actions in RT suddenly the CPU load jumps up again to 99
and stay’s there.

Any clue what could be causing this?

Regards,

Met vriendelijke groet,

Nope. I’d look to see if it’s doing database queries or not, whether
it’s swapping, and then possibly strace the process to see what’s being
slow.
