Problems with concurrent acces to Apache/DAV/SVN
Hi,
our machines (app. 100) access a subversion server via the Apache DAV
module. As the number of concurrent accesses to the webserver grows, the
apache gives some errors:

When we did the accesses manually today, there were no errors. So it
seems as the problem occurs on many concurrent accesses.
I don't think it's really a space problem, here the df output:

I recommend you upgrade to Subversion 1.2.3 (and 1.3.0 when it's
out), and convert your repository from BerkeleyDB to FSFS.
