Glad the project is back, but my first new WU was another N-Body task that failed within a few minutes. The task is gone now, but here is the message log for its brief existance. Anybody know what is up with these?

I don't see any error here?

Every time the n-body task restarts in BOINC I get a Windows error message, "Task ended in error". I sometimes get 30 or 40 of these before the WU gives up with about 10 or 20 minutes of actual CPU time (compared to 300+ hours estimated run time when it downloads). BOINC task list shows "computation error" for the task at that time. All my n-body WUs have had this behaviour for several weeks now.

Just an observation: the BOINC message list shows the task restarting, but doesn't ever show it stopping. It appears to be Windows that kills it. Also note that no other tasks are show starting in between the MW restarts (this machine has 2 CPUs, and usually runs 3 or 4 different projects).

I've tried reloaded the C++ library, as suggested in another thread. Just got another n-body WU, waiting to see what happens with this one.

OK, here is the windows message I receive:

"milkyway_nbody_0.40_windows_x86_64_mt... has stopped working

A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solution is avialable."

I have 20 of these right now. 21 by the time I had typed that. Up to 23 just before I sent this.

Here are the associated BOINC messages:

According to the BOINC tasks tab the WU has been running for 44 seconds. I expect it to die shortly.

WU died at 01:08 cpu time. BOINC task tab says "computation error" but messages tab just says

Here is the database info for that WU:
