We are seeing frequent but intermittent java.net.SocketException: Connection reset errors in our logs. We are unsure as to where the Connection reset error is actually coming from, and how to go about debugging.
The issue appears to be unrelated to the messages we are attempting to send.
Note that the message is not connection reset by peer.
Any suggestions on what the typical causes of this exception might be, and how we might proceed?
Here is a representative stack trace (com.companyname.mtix.sms is our component):
