DefaultAppPool

IIS 6.0 is hanging every so often, with the following error in my event log
... and i'm not having much luck in figuring it out...

A process serving application pool 'DefaultAppPool' exceeded time limits
during shutdown. The process id was '2604'

any help is greatly appreciated...

... a litlte more info ...
this ONLY happens on the SSL part of my site
and performing a "recycle" on the DefaultAppPool fixes the problem, but
kills all current sessions.

Regarding the original question of "A process serving application pool
'DefaultAppPool' exceeded time limits during shutdown" -- Sounds like you
are running an application that is "hanging" on shutdown.

IIS6 waits for 90 seconds on default (configurable) for an application to
shutdown when it's supposed to recycle, after which it'll kill the process
anyway. When you get such an event log entry, it means that SOME
application inside the application pool took longer than 90 seconds to shut
down. Now, this may be expected -- for example, you're allowing people to
download 4GB of data and the app is busy serving that and takes longer than
90 seconds. Or, it may not be expected -- for example, you're running a bad
ISAPI that mishandled async communications and leaked some ECB. You'll have
to investigate further (isolate your applications, for example), to figure
out what is going on.

FYI: this is not "IIS 6.0 is hanging every so often". IIS6 is NOT hanging.
If it was hanging, you wouldn't get the event log entry. Now, what you are
running ON IIS6 is hanging. It's like when you run a program on Windows and
the program crashes, is it "Windows crashed" or "that program crashed"? Or
if you run a buggy video driver that blue-screens the OS, is it "Windows
blue-screened" or "the device driver crashed"?
