That's an interesting story. Now 5000 msgs is different than just 10. But if it happens with 10 messages at a time, things might be more reproducible.

There was sometimes "Broken pipe" error and several problems with some DLRs (PDU unpacking failed). I tried to reproduce this problem but I was not able to get those errors anymore, it was happening one time when there was a huge traffic. Tomasz.
