Hi,
I'm running SVN 1.4.2 via an Apache HTTPD 2.0.55 over webdav. This is on
Solaris 10 SPARC.
Some checkouts/updates seem to hang. The request in question involve
checking out a directory worth 350 MB. When I look at the Apache worker
handling my request I see that it accesses the revision in which this
directory was created:
# pfiles 74911

Descriptor 26 ist the revision and 24 is my client connection. When I
truss the process I see repeated patterns like this:

My interpretation is that the process does read the revision continuesly
and answers back to the client, but very slowly. Checking out via
file:/// access does work.
Any idea, what's going on here?
Thanks,
