It seems that if I do a svn up on a working copy with lots of
svn:externals (including some externals that have externals of their
own), over svn+ssh, subversion keeps all the ssh connections open until
it's done updating the whole working copy. I don't see this one in the
issue tracker.
There are 25 svn:externals in all involved in checking out this tree. The
tree root has 17 externals, 3 more are in a sub directory (which is itself an
external), and a subdirectory of that sub directory has the rest.
I was doing the checkout on the subversion server, and accidentially
using svn+ssh despite the fact that most repos were local. At the same
time, on a client, I was doing a svn co of the same tree.
The result was that several hundred processes were spawned. Below is an
example of what the relevant parts of the process tree looks like if I
only do a svn up on the server. Running it on the client too doubles the
number of ssh server processes and svnserve's.
At this point I think I was at about 350 processes on the server, which
normally runs 100. (Unfortunatly, I had gone to bed at this point). Then
this point something else pushed it over the top and it died of process
starvation. I have not reconstructed the details but it was not able to
run user processes this morning, though I was able to ssh in as root and
kill a logjam of svn processes and postfix processes.
Anyway, I hope that in the future subversion can free resources
associated with checking out externals once it's done with them, rather
than waiting until the end of the whole checkout to clean up.
