Re: Windows 'Access denied' errors

Hello D.J.,

Lately, since 0.30.0, I have had more problems with Subversion than
previously. Up to 0.29.0, I did not have many errors of this type.

Yesterday, I was playing some MP3 using the Windows Media Player. WiMP
uses from 5 to 30% of the CPU time. I thought that by lowering it's
priority, I could lower the frequency of those errors. I thought I had
something there, but it looks like this is not true.

This morning, I just committed a few changes to my repository, and here
are the results:
K:\jobnudge-issues>svn commit
Deleting assigned\fbos\0011
Adding resolved\0011
Deleting resolved\0011\resolution
svn: A problem occurred; see later errors for details
svn: Commit succeeded, but other errors follow:

Subversion was supposed to tell me more, but it never did so. I did get
an application failure (a GPF), but did not note it. Sorry about that.
Before 0.30.0, I never got those GPFs. There must be something more that
changed in 0.30.0 with regards to previous versions.

I will check those services and try to shut them down and see if the
frequency of the access denied errors changes.

Will report back with more data next time.
