Aha - yes, we are running windows 64 bit server. We use subversionnotify
for pre-commit hooks but by default there is a post commit hook that I
guess could be doing a diff so this looks very promising. When 1.7.2 is
released via SVN Edge I'll re-instate the post commit hook (just to

Thanks for the response Mark.


Thanks also to Stefan & Markus who also pointed out that it was not SVN
that calls svnlook.exe - I removed the post commit hook (not used
anyway) and so far so good.

        Since upgrading to 1.7.0, and 1.7.1 via subversion edge, about
half the commits being done by users (via tortoise) result in the commit
hanging after most of the work has been done. Whilst hung, the
repository shows the commit has taken place, but on the server
svnlook.exe is hogging all the CPU. Killing the svnlook.exe process
allows the commit to continue (normally).


Is the server Windows 64-bits?


There is an infinite loop bug that is fixed for 1.7.2 that can occur on
Windows 64-bit with diff algorithm. So if you are making a diff for a
post-commit email or something like that it could be that you are
running into.
