2 of my LHC wu's have exited with the following windows error message (Fortran),
"The process cannot access the file because it is being used by another process (Createfile, erno=32, unit=92)."

When I accept this message the cc produces the folowing messages,

Get BOINC WIKIed

One of my WU's stopped unexpected, but it continued to process without a fortran error (see bolded lines of the messages):

Digitalis ... can you send me your complete log file?

p.d.buck@comcast.net

Thanks ...

LB,

You got hit by a bug they have been chasing for a long time. As near as I have been able to tell it is a timing thing as tasks are started and ended and the BOINC Manager/Daemon and the Science App talk past each other.

So the Daemon sees the Science App exiting (for whatever reason) and it says "Oh, you are done and have a zero status (no error) so it must be finished... where is the Result Data File? Oops, no finished file ..."

Yet the work will either restart on it own as it needs to ... or it gets picked up later after a restart and it completes ...

Be glad to, which particular file tho? (hangs head in shame)

Well, it is in your BOINC directory ... on windows it is the
c:\program files\boinc directory. The 4 files are named "something.txt" and one has "something.old", make a copy, zip them up and send them too me ...

On the mac they are in \library\application support\boinc and have the same names. I don't know for sure where they are in Linux.

I will be making a longer plea later today in that I have discovered how few messages I have data on ... I spent the better part of yesterday looking for more messages in the code (and I am not sure I got them all, even now ...)

Done, if its not correct let me know.

Good luck with your project.
