Just about to do that.

Well, the machine has a serial console; I hope I do not have to go to
the office then ;-)

Well, I have only the given config: dual Xeon plus HTT (4 procs
virtual). Might it help to turn of HTT?

options UFS_ACL is in the kernel, but I don't use anything like that,
the setup is pretty plain and my kernel differs from GENERIC in removing
unneccesary devices and adding the NO_SWAPPING option, since I don't
have any swap space.

I did not have the setup running on 4-STABLE - sorry. I'm a little bit
worried up running the machine on 4-STABLE; but since the BIOS offers
something like "OS is not ACPI aware" I guess I will have no big
troubles.
[several minutes later]
OK, I booted a kernel with INVARIANTS. At least in 10 minutes of feeding
mail into the machine it did not panic. It is a lot slower (although I
do not see the CPU time going up too much, it might be an I/O related
issue). The mailfeed I give to the machine is a copy of a real mailfeed,
I cannot let this feed up for hours in this configuration, because I'm
going to build a backlog on the production server and put too much extra
load on it.
The problem (of course) still exists. What can I do to give more
information now?
