I recently posted this message (follow-ups included below it) to the
users_at_subversion.tigris.org email list. I haven't been able to find a
solution, and I'm hoping someone on the dev list can point me in the right
direction.
Any suggestions?
Thanks,
Vince

Subject: memory problems w/ mod_dav_svn?

Has anyone run into memory problems using mod_dav_svn w/ rather large
repositories?
I recently migrated our repositories to 1.5.1 and moved them from svn+ssh
to mod_dav_svn via https.
After one of my users checked out the largest project (about 800MB
checkout), our SVN server ran out of memory and the kernel had to kill
processes. I was able to recreate the problem by checking out the same
repo again and watching top on the server. This is a snippet of top
*after* the checkout completed:
PID USER PR VIRT RES SHR %CPU %MEM TIME+ CODE DATA nFLT
nDRT COMMAND
19167 apache 16 1655m 1.4g 2664 0 36.0 3:59.93 288 1.4g 0
0 httpd
In this case the system didn't run out of memory, but the httpd process
that served my checkout didn't seem to give back the memory it used during
the checkout process.
I really don't want to have to move back to svn+ssh as the transport,
because I like not having to give system accounts to the engineering
staff. We're also using mod_authz_svn because we need to restrict
repository access to outside consultants.
Can anyone offer any insight?

For what's it worth, I just tested the monstrous checkout w/ mod_authz_svn
disabled, and I still get the apparent memory leak.
So the problem lies either in mod_dav_svn or possibly mod_dav.
Does anyone have any suggestions on how to figure out which module is
causing the high memory usage?

The reporter was having the problem happen during merge, but the fix
was in a general area of code. It was related to authz handling. You'd
have to apply the fix to the 1.5.1 source and build yourself.
