Never with Tomcat but we might have a different number of threads. But

Yup.. thats the problem we had. But we have too many threads so
Linuxthreads fell down.
It sounds like upgrading your glibc would fix this issue.

I think this particular bug was fixed in 2.3.3 but there are other
interesting bugs fixed in 2.3.4 so we went that route. That and Debian
has no 2.3.3 build.

Yeah.. these should related. I mean its a race condition so the
processor or schedulre might affect it.
So... this might be another Opteron issue that we've solved :)
I'd be interested in finding out if the switch fixes this issue..
