IDENTITY PK-FK corruption of data

Hi All,

I have a problem with a DB2 server of my customer. It is a Debian
Linux running DB2 Express-C. I have an IDENTITY field as PK in a table
and I use this value as FK in another table. Two weeks ago the FK
values got corrupted or mixed up somehow. I also got some warnings
about system tem****ary table spaces so I created a 16K page size
system tem****ary table space to be sure. All seemed to be okay until
today. Something happened an hour ago and the FK field now holds
corrupt data. The guys at the local IBM sup****t say that it is most
likely that the client program connecting to DB2 has something to do
with it. I think it doesn't fit the situation becasue the client
program has been shut down for the weekend and it still is besides it
never updates key fields at all. Has anyone seen something like this
before? What can I do?

Thanks,
Sandor
