dunno that one...

how's it run with it off? long shot...

but you know your connections aren't being reset or closed
properly...

are there are other processes at play? is it based on number of
users? total amount of traffic (sum)? how can you reproduce it?

yeah, that should just kill the server if you have a bad loop or
something, but you never know...

no, i was referencing your coding methodology in case you have
any custom components on there your guys may have written...
check those to make sure they kill off anything that touches
memory in the opposite order that they called it, making sure to
free up all memory and thus abort memory leaks... yeah, way too
general...
but yeah, if you can roll your server back in time to a point at which
it was stable and then keep adding stuff... got a crash server you
can configure to do this?

oh, you tried that... ummm... yeah, them IIS lists can be great...
