Well, the machine has a serial console; I hope I do not have to go to the office then ;-) > 1) is anybody _not_ running an i386 or MP machine ? Well, I have only the given config: dual Xeon plus HTT (4 procs virtual). Might it help to turn of HTT? > 2) is anybody using MAC ? 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. > 3) has anybody noticed this before on 5.x ? 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? - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
