ISC ERROR CODE:335544345

ISC ERROR MESSAGE:
lock conflict on no wait transaction
deadlock
update conflicts with concurrent update

STATEMENT:
TIB_Statement: "dmHost_2.DSModule.tblWebUser.<TIBOInternalDataset>.<T
IB_UpdateSQL>.<TIB_Statement>."


What triggers this error? I did not do any concurrent updates, in
fact, I have a critical section that ensures all the threads that
perform updates are serialized.

My transaction component is set to autocommit = false, but I call
Commit explicitly every time after an update is posted.

The weird part is, I have 4 threads running, all doing the same
thing but updating different records in the same table (again, they
are serialized when they perform updates) and only one thread
faulted with this error, the rest continued without any problems.

Is this a firebird bug, or an IBObject bug?

Thanks in advance,
Zach
