שלום עידו
אני שמח שיש כאן מומחה

שעובד בשעות עבודה נורמאליות ולא לפי שעון ארה"ב
האם אפשר יהיה לשאול כמה שאלות אותך בטלפון - אני די חדש בכלי הזה
אגב, גם אני לשעבר מאינטל (פ"ת) לא עשיתם שימוש ב-

Subject: RE: Tortoise (1.5.5) commit failed on large commit
It looks like we found the root cause.
There is conflict with MacAfee (version 8.5) that cause to large commit to fail.
When we define the working copy, or even just the .svn folders as "excluded" for MacAfee scan, the problem is solved.
At may be just workaround for now, but at least we know how to solve these errors.
Thanks all for the help,
Ido

YQW... It's quite possible something did... There's enough new code
in 1.5 that there could easily be enough of a different execution
path
than was previously that where you hadn't run into a timing problem
before, or yet, it was close enough you're getting it now. I'm more a
user than one of the developers, though, so one of those that's run
the code in conjunction with a profiler could give a better answer.
It could be informative, if you still have a machine with 1.4 or can
reinstall it, to do the same type of FileMon run with that and
compare the average intervals between the file operations, whether
they're significantly shorter or longer a time between, especially
around the point where 1.5 fails. You could also track network
packets to see if those are stacking up around the failure point.
If all the clients are using the same network card, you might want
to see if there's a more recent driver update for it, as it could be
the bottleneck. Another thing you could try is enabling svn://
access also and see if that helps, as it's possible something in
the WebDAV module is contributing also.
Good luck,
Mark
