Increased number of "Connection reset by peer" after Gerrit 3.5.1-73 upgrade

[David Åkerman]

Hi,

After upgrading Gerrit to 3.5.1-73 we got an increased number of Connection reset by peer that looks like:

[2022-06-22T00:22:56.652+02:00] [NioProcessor-1] WARN  org.apache.sshd.server.session.ServerSessionImpl : exceptionCaught(ServerSessionImpl[<username>@/<ip>:<port>])[state=Opened] IOException: Connection reset by peer

We suspect that the upgrade of sshd-mina from 2.6.0 to 2.7.0 caused this.(https://gerrit-review.googlesource.com/c/gerrit/+/330659/14/tools/nongoogle.bzl)

Is these log entries something to worry about or can we safely ignore these and filter away warnings from org.apache.sshd.server.session.ServerSessionImpl?

Best regards,

David

We have that on latest 3.4, but we use default nio2

Thanks for the response!

Yes, we got this warning before also. What we were worried about was that the occurrence increased much after upgrading to 3.5.1-73.

In the end we decided to filter away these warnings because we thought that this was something we could safely ignore.

+1, we have the exactly same warning after upgrading to 3.7.3, never see this before.
