SEVERE: A: resending of 8688 failed; entry not found

Hi all,

When I use a single client to issue requests to the raft group, it works fine and the peak throughput is 3500 requests per second on my laptop. However, when I have two concurrent clients to issue requests to leader A, I found that the performance significantly degraded and I saw the following message at the leader A:

Oct 01, 2015 12:33:54 PM org.jgroups.protocols.raft.RAFT resend

SEVERE: A: resending of 8688 failed; entry not found

Oct 01, 2015 12:34:34 PM org.jgroups.protocols.raft.RAFT resend

SEVERE: A: resending of 67266 failed; entry not found

Do you know what happened there?

Thanks,

   Cheng

Now, I found that even with a single-threaded client, the problem showed up.

Thanks,

Hi Cheng,
Do you have a program which reproduces the issue ? If so, can you create
an issue in GitHub
and attach the program so I can take a look ?
