ORA-29516: Aurora assertion failure: Assertion failure at eoamrk.c:234

Question

We are hitting an assertation error in Aurora.
The system is Oracle 10g R2, 64 bit, running on RHEL.
Have searched the forums and googled for this - although ORA-29516 is found they are related to other issues rather than within eoamrk.c
Does anyone have any further information on this? For example, is ORA-29516 definitely for 64 bit systems only (we can't reproduce the issue on our 32 bit system), but it occurs repeatedly on our client's system, which is 64 bit.
The exception occurs when a large number (20k+) of updates are made to a table, and they call update triggers which in turn call Java methods which send out the changes to using RMI.
The stack trace is below (apologies for commenting out the confidential bits - they don't matter anyway).
Many thanks in advance for any advice or suggestions, particularly workarounds.

Colin,
Pardon me if I am stating the obvious, but have you tried MetaLink?
Good Luck,
