Subject: AW: AW: [suse-oracle] Kernel Bug
Hi Warren,
Hi Arun,
As we saw while googling for this bug, IBM-DB2 is having the same problem
with exactly the same problem: aio.c:733.
So it's not only an suse-oracle-problem!
Bye
Frank

Betreff: RE: AW: [suse-oracle] Kernel Bug
Thanks Warren,
Is there anyone who nailed this kernel bug in non-database environment
i.e. some sort of aio program?
