Hi,
first thanks for your answers.
Now I found some ECC-exceptions in the Kernel.:
EDAC MC0: CE page 0xfeb8e, offset 0x0, grain 4096, syndrome 0xb32, row 4, channel 0, label "": e7xxx CE
EDAC MC0: CE - no information available: e7xxx CE log register overflow
EDAC MC0: CE page 0xfeb8e, offset 0x0, grain 4096, syndrome 0xb32, row 4, channel 0, label "": e7xxx CE

This is on both servers, production and backup. Right know, I'm updating the Kernel
to 2.6.22.1. Hopefully this helps :/. But I think there is no hope.
There are also Traces in dmesg:

The hardware is 5 years old... It was not possible to get new hardware

SIG 11 (ie SIGSEGV) is pretty much the typical "generic crash"
indication. It most likely means you ran into a software bug or
corrupted data. There is no reason at all to think that it's got
anything to do with transaction ID wraparound --- that message is
only coming out because it always comes out at a database restart.
What you ought to look into is what *did* cause the crash. Did it
produce a core file, and if so can you get a gdb stack trace from
the core?
