WU in some sort of loop
Is this considered normal behavior and should I let it continue?

It looks pretty hopeless.

Re: WU in some sort of loop
That sure looks like an endless loop to me. I would reboot. If the loop continued, I would then Abort the Task.

Re: WU in some sort of loop
I just happened to catch it one time and what happens is the disk light comes on and stays on for several minutes. Task manager shows that the only process doing I/O is BOINC.EXE. Evidently during this heavy I/O period, it doesn't talk to the science processes and all four reset back to the beginning of the job they were working on. Task Manager shows ~26,000,000,000 I/O bytes for BOINC.EXE and ~1.5 million I/O Reads. Single largest process when sorted by I/O Reads

Re: WU in some sort of loop
Looks like a know issue but no resolution. Berkeley has ticket 336 open:

Problem with the heartbeat mechanism: if the client does something that blocks for > 30 secs (e.g. a synchronous DNS lookup, a disk-space scan, a debugger break) then all apps quit, producing confusing messages and possibly wasting CPU time.

Proposed solution: remove heartbeat mechanism. Include client process ID in the app_init_data file. The API periodically sees if that process is still alive, and exits if not.

Between not being able to upload results and not being able to run the science, this isn't a very productive project for me. I think I'm going to take my cue from the science and EXIT...
