I'm having a strange problem on our Linux research computer. My collaborator logs in remotely using TeamViewer to run Mathematica.



We are running RHEL6, TeamViewer 12, and Mathematica 11.



We have been running calculations this way for a year, and had no problems until last month.



What happens is that after some period of time, my collaborator's gnome-session jumps to 100% CPU use. At the same time, the .xsession-error log grows continuously to enormous size--it will fill up the 150 gigs or more if we don't delete it.



If I run tail on the error file, this is what I see:
_IceTransSocketUNIXAccept: accept() failed
_IceTransSocketUNIXAccept: accept() failed
_IceTransSocketUNIXAccept: accept() failed
_IceTransSocketUNIXAccept: accept() failed
_IceTransSocketUNIXAccept: accept() failed
_IceTransSocketUNIXAccept: accept() failed



I tried chmoding the error file to prevent writing to it, but the system just generates a new one. And regardless, the 100% CPU use by gnome-session is massively slowing down the machine.
