         Environment: OS: windows 2008 R2 x64, AIX 7.1, possibly other
JVM: SUN/Oracle 1.6.0_24 server x64, IBM J9 Java5 vm2.3.sr12.j9vmap6423-20100630, possibly

Hi

In my case I am inserting many many rows in a in memory derby DB. After a while (a few minutes)
I get a "SQLNonTransientConnectionException: No current connection" and the derby.log (see
attachment) contains a complaint about an invalid page format with a dump of the page in question
(which is completely zeros). The derby.log also contains another entry before the error (usually
the same time stamp as the error): Cleanup action starting
Maybe this is related to the error.
Please find attached a test case to reproduce the issue. Just give it enough memory (-Xmx4g).
It will insert a lot of rows to an in-memory derby DB with several threads over several connections.
In case you want to run only one thread with one connection you might want to set these properties:
 -DuseSingleConnectionOnly=true -DuseSynchronousCommit=true -DnumberOfAsyncThreadsPerGenerator=1
-DnumberOfGeneratorThreads=1 -DnubmerOfRowsPerThread=100000000 

Thank you very much
Christian
