1. Re: NAKACK errors on retransmit when cluster is under heavy
belaban Feb 21, 2007 1:31 PM (in response to hmesha)It is an intermittent issue, when a retransmission request arrives for a message that has not yet been added to the retransmission table.
I assume those warnings are intermittent; they don't cause further problems,do they ? -
2. Re: NAKACK errors on retransmit when cluster is under heavy
brian.stansberry Feb 21, 2007 1:47 PM (in response to hmesha)Bela, I noticed in the error msg the requester and original_sender all appear to be the local address (assuming the hidden subnet is the same). Is that expected?

belaban Feb 21, 2007 2:03 PM (in response to hmesha)Yes, that can be expected. Especially if loopback is enabled

hmesha Feb 21, 2007 3:15 PM (in response to hmesha)Bela,
Thanks for the prompt response. I'm not sure if it's intermittent or not. I asked my QA person to rerun the test to confirm that and I'll report back here.
Tthe loopback adaptor are enabled on the machines as Brian noted and the fact that the requester and the sender ip address are the same in the error makes me think that's not affecting anything since there's no lost messages, techincally.
Again I asked our QA to perform a second test with loopback disabled after the first test mentioned above to confirm that the error is not showing anymore.
Will report back.

5. Re: NAKACK errors on retransmit when cluster is under heavy
belaban Feb 22, 2007 4:27 AM (in response to hmesha)What I meant was that if this was not intermittent, then the process would stop delivering messages due to the gap in sequence numbers. This does not appear to be the case
