Hi,

We have a local master and a slave on Amazon. Normally the replication works fine but in the error_log we always have the exceptions like below. We don't specify the timeout setting in replication.config or sshd_config and only put the url and threads in replication.config. Any idea about what may cause this? Thanks.

Looks like you are hitting network issues while replication plugin tries to push to a slave

Which Gerrit/JGit version are you running ?

I see the same error during replication for some projects.

I remembered that I fixed it by "git gc" & "git repack" with some arguments such as '-a', '-F', or '-f'.
