SVN issues -- errors during transfer

We’re experiencing some problems from one or two users during SVN checkout and/or update processes.
The problem appears to affect only one or two users, and it never happens in the same place twice.

We’re running Windows XP (SP3) and TortoiseSVN 1.6.6.

When performing a checkout or update, the process will halt with an error
REPORT of ‘/dbname/!svn/vcc/default’: Chunk delimiter was invalid (
(proper dbname and server name redacted)

Searching for the SVN error seems to point to problems with Apache ( bug/275643)


This seems to be bourne out by some of the HTTP access log entries around the time of the SVN checkout

[Fri Nov 06 14:41:02 2009] [error] [client] Provider encountered an error while streaming a REPORT response. [500, #0]
[Fri Nov 06 14:41:02 2009] [error] [client] A failure occurred while driving the update report editor [500, #190004]
(This link assumes the server is running on Mac (OS X Tiger), but the errors are identical)

I can’t seem to work out which version of Apache you’re using though.

Has anyone else experienced these issues?
