Geholfen hat nur DB löschen und neue Replik anlegen. Seitdem ist der Fehler nicht wieder aufgetreten
Im PMR wurde von IBM auch nichts anderes empfohlen, die Problemursache ließ sich nicht wirklich genau lokalisieren:
"I have receievd the following reply from our development team:
I believe it has nothing to do with your operations, and if you recover
it from backup, the issue shouldn't be reproduced on the same databases
in a reguralr way. Otherwise, we need to fix this problem.
There're too many possible causes, e.x. memory overwrite, timing issue,
hardware broken, etc. Many tasks, such as compact, fixup, updall,
running in the meanwhile may have an effect on multi-databases. Though
you don't make any possible tasks run on your old db, it also could be
affected by some of these tasks which constitute a complex high load
running environment. Or, though it's rarely, bad disk-track or bad
sector on your hardware may occur."
