This was posted earlier, but doesn't appear in the Known Problems list that I just looked at...

I've been noticing that BOINC will try to switch tasks running on one of my Linux boxes that just got a few tasks from session 1042. When the task switch happens, the blender process isn't stopped, so there's a background process that is contending with the running tasks.

If I stop BOINC on the whole machine, all the processes terminate correctly, but not if a task switch happens.

Since there are short deadlines for BURP, BOINC seems to like to swap things around and start/stop tasks frequently.

Currently running BOINC client v6.10.56 on 64bit Ubuntu Linux on a quad 6600 CPU.
