Answering my own mail. Seems to be faulty ram-modules.

Removed all eight modues and swapped four 1 GB 3200 ECC modules from
another server (exact same 1 GB module from Corsair). Recompiled
kernel without problems.

Added four modules from current server to a total of eight, compiled
world with -j 5 and compiled kernel, copied large file from another
host to do simple stress-testing. Currently no signs of problems.
