Is there anyway to aviod Connection Reset Exception?

When i tried to open a session with _SSHClient_ and send a shell command to remote server by socket ,sometimes this _Connection Reset_ exception will arise!
So i searched this keyword in issues, found one, but it isn't my issue, my _SSHClient_ was enabling keep alive, so i can't figure out what else i can do.
ps. My _SSHClient_ was stored in a local map just for recycle
