The leak is quite problematic on a large network. I've taken
preventative measures by increasing the number of file descriptors for
the cfservd process and restarting it every morning, but 1 year from now
when I've got 10,000 clients (or more), this will mean having to restart
cfservd midway through a scheduled cfengine run just to keep it from
crashing, as the process will try to garner over 20,000 file handles
that it refuses to release.
I fully understand the complexity of locating leaks like this (I've
dealt with my own leaky programs), but I sincerely hope that "just
restart it once in a while" is not the accepted solution to the problem
and that some time is devoted to locating the leak.

Looking at my own sytsems I can see a slow growth of VM size over 3
months, on a busy server, nothing dramatic. I suggest that you randomly
restart the daemon to avoid this. That is what we used to do for dns
which has a much worse leak. Debugging this is not easy. I have gone
over things many times. It could also come from some third party library
like openssl or berkeleydb. It is very hard to know. But it is not a
serious problem. This is not going to tax anyone's servers.
