Description Franz Sirl 2007-08-08 05:13:49 UTC 
After saving an edited file in TextPad to a samba share, TextPad was unresponsive. Checking on the server showed high load for one smbd (25-100% CPU). Killing this smbd allowed everything to continue normally. I made a level 10 debug log though.

Patch

Can you try this patch? I think this should fix it.

Thanks a lot!

Looks very good! I rebuilt from the SAMBA_3_0_25 branch and so far I couldn't reproduce it anymore with roughly the same setup (TextPad+Explorer+TortoiseSVN) that provoked the bug reliably before.

Thanks for the fix.
Actually I catched this one by accident while trying to track down the corruption bug with VC6. No hard data yet (well, according to tcpdump it doesn't happen on the wire), so no bugzilla entry yet.
