MQ 8.0.1 JCA Resource adapter for Weblogic 10.3.4 on Linux

Hi

I have problem with subject - messages get lost.

I have tested it in many ways and it seems to be load related issue.

1. Test #1

With  Sonic test client i send messages manually "at low rate" - everything is OK.

2. Test #2

Same test but I click faster and response messages start to get lost.

One of ten or so.

3. Test #3

Jmeter P-T-P test, every fift and up to all response messages are lost.

In debug log is

Debug: SonicServerSession.onMessage() entered on [ACTIVE] ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)' getAccount;111111
" delivered with deliveryCount 1
SonicSampleMDBWithReply.ejbCreate(), bean instance 164136676

Any help is appreciated since I am out of ideas at the moment.

Regards,
