Hello,

I've been seeing some strange behavior for the last few days, and I'm
not sure what else to do to troubleshoot it. It started when two of my
puppet clients (always the same two) suddenly began to take forever to
finish their catalog runs. I'm not sure what changed around 5pm last
Thursday to cause this, but well, check out the logs...

Apr 30 16:50:50 emsdb01 puppetd[11363]: Finished catalog run in 4.59
seconds Apr 30 17:26:29 emsdb01 puppetd[11363]: Finished catalog run in
292.65 seconds

Apr 30 16:43:05 emsweb01 puppetd[1345]: Finished catalog run in 4.47
seconds Apr 30 17:18:27 emsweb01 puppetd[1345]: Finished catalog run in
292.53 seconds

Now when emsdb01 and emsweb01 are checking in, all the other clients
seem to queue up behind them.  So I end up seeing...

Conection timeout calling puppetmaster.getconfig: execution expired 

And...

Could not retrieve catalog: Connection Timeout

from all the other clients. For those that don't time out, I see a
flurry of "finished catalog run" as they all complete at the same time
(but with excessive catalog run times, presumably because everyone else
got held up by emsdb01 and emsweb01).

When I run "puppetd --test --debug" on emsdb01 and emsweb01, I don't see
anything unusual happening. Both servers are basically idle while the
catalog run is happening. What I do see is that they get hung up on
these tasks for some reason:

debug: Calling puppetmaster.getconfig
debug: Calling fileserver.describe

When I look at the puppetmaster as this is going on, I don't see
anything unusual in regards to server load there either. At first, I
suspected some kind of network connectivity issue, but I have run
several tcpdumps, and everything seems to be connecting fine. Is there
something else I should be looking at to determine the cause of this
problem?
