Subject Re: Random DRDA Error on IBM J9 JVM
Date Mon, 19 Mar 2012 17:18:32 GMT
Thanks Peter.

Do you remember if you upgraded to 10.8.2.2 or 10.8.1.2? We do have a test
environment with 10.8.1.2, and are seeing similar results. I do agree that
it seems to be a strange coexistence with Derby and J9. The IBM Classic JVM
doesn't seem to have this issue, although IBM seems to have eliminated it
in V7R1M0.
