We have a windows client (connected to a unix server) whose Xgo process is using an inordinate amount of server cpu - up to 16% at times. The owner of this session is not able to identify any particular activity in his session that would cause this much cpu usage; other users' Xgo processes consume much less (< 1%). This session's excessive cpu usage causes other user's session to be sluggish. The only solution we've found so far is for the offending user to restart his session. Any ideas?
