Did you look at your Threads setting too?
I'm not sure abount Pound 2.7, but I think
the 2.6 version uses a pool of a fixed
number of threads, based on your configuration;
the default value could be too low for
your increased load.

For the past month or two I've been dealing with an issue where pound
will randomly hang for several minutes, and then eventually correct
itself. Manually restarting the process will also correct this. I think
it has to do with the load on the server. We increased the load in the
time frame mentioned, though not by anything unreasonable. I spun up a
new VM and tried both the custom PCI version from github as well as the
latest stable 2.7 release, but both have the same issue. We were running
several sites plus Exchange OWA/ActiveSync/Outlook Anywhere on the
system, but as of Thursday are only running Exchange services, and the
problem persists. Exchange services are where the increased load came
from as we are now running 20 or so laptops through Outlook Anywhere
constantly, as opposed to maybe half that before. I tried increasing the
number of files open allowed, per a mailing list thread from some time
back, but it's still having the issue. I am monitoring it with a script
I wrote to check for availability, which will email me and restart the
service if it's down. Everything was fine from last evening until around
8 this morning, when people started working again, so it seems it's
connected to the Outlook Anywhere connections, since that's what would
have started around that time this morning. ActiveSync runs 24/7, so if
that was the problem it shouldn't have stopped hanging during the
off-hours. I don't see anything in the logs that appears to be helpful,
so I'm hoping someone here can suggest a debug log setting or a fix, or
anything. Log level is currently set to 2. Is there a way to get more
information than that?
Thanks,
