Comment 34 for bug 36581

Brand new install of Kubuntu
No networked devices, nothing under /mnt at all
Root is xfs, /home is xfs, /boot is ext2 - all partitions on a single HD (400Gb Maxtor)

gam_server is constantly using ~16% CPU and repeatedly writing to .xsession-errors

Failed to process 26 bytes from server

This file is growing at a rate of about 1Mbyte every 10 minutes

I think this may be a separate bug to the original 'lots of files under /mnt' bug, but it's the same as a few people have mentioned above.
