Reappearing messages with qpidc and bdb persistency store

Hi all,

Every now and then, when I restart my qpidc broker (version 0.22) some messages reappear in the queues, although they were long since taken from the queues (and committed).
Something like that (qpid-stat output):
queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind
==============================================================================================================================
some_queue_or_another Y 0 125 125 0 1.31k 1.31k 1 5

I then restart (qpidd --quit; qpidd --daemon --load-module ....) the broker, and I get something like this:
queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind
==============================================================================================================================
some_queue_or_another Y 125 125 0 1.31k 1.31k 0 1 5

Queues are created like this:
qpid-config add queue some_queue_or_another --durable --argument=qpid.priorities=10 --file-count=16 --file-size=512

As said, sometimes the messages magically reappear, sometimes they don't. I didn't yet get the pattern when or why.
I use transacted sessions, and I am sure, that all messages get committed OK.

Did anybody else have some similar problem?

Regards,
Ales
