We have found v11 to be very sensitive to "rogue" clients. On day 1,
we had this problem when a few 2004 clients would try to connect. We
think a corrupt "Caches" folder may cause it too. Most recently we
had an issue where a couple of clients on a unreliable wireless
connection were causing the same problem. We ran wires to these
computers and the problem went away.

I have seen these on our dev server with a very small cache (100-200MB)

I have only seen this on a G5 (not any PowerPC, just G5s), but we do
not have any windows clients. Have you ever seen it on an intel Mac?

I'm not sure I'd go that far, but I hope those non-production members
have tested their applications under load and under load for several
hours as some of the issues being reported on the list can take hours
before showing up.
