Greetings!
I have a puppet server and client, both running version 0.24.5. They
are running atop debian/lenny, in openVZ containers. (As such, I can
(and to some degree must) readily monitor tcp socket counts and buffer
sizes).
I have the following in a class file:
file { "/usr/local/xyz/etc/keys":
mode => 644,
owner => "xyz",
source => "puppet://puppet.mydomain.com/files/xyz/keys",
recurse => "true",
}
The directory has about 700 files in it. It used to have 1400, but I
trimmed it down...
It appears that the client application opens a tcp socket for every
one of those files when it runs, as it computes the checksum. When it
hits 1024 sockets open, it is unable to open additional sockets. This
shouldn't be a problem, though... after all, I only have about 700
files. But, unfortunately, when it completes its run, it doesn't
release the sockets. :-( Therefore, 2 runs and ... yeap ... it's
done for. I suspect that if I reconfigured the box such that puppet
ran from cron, I would have a workaround. That said, I doubt this is
the only time someone will try this.
Here are my client logs:

Incidentally, the server never reports more than 188 tcp sockets open.
I'm guessing y'all would like more data. If you can point me to
specific instructions for obtaining said data, I'll be happy to
respond. Many thanks in advance for any help you can provide.
Sincerely,
