Syslog Messages - Read from socket failed: Connection reset by peer

Hi

Was hoping to get some insight as to what these messages mean  - I am seeing them on my Syslog server coming from my Aruba Controller - the messages tend to repeat multiple times.
The messages appear all related to SSH - is this perhaps a something trying to login and can't?
Model: 3600
Firmware: 6.4.4.6

Are you the only one that can SSH into your controller?  It looks like a misconfigured SSH client.

Hi

Yes I am able to SSH to the device - me and my coleague has SSH access.
Judging from the time stamps it is all during our none workling hours.

I am suspecting our Monitoring system maybe trying to connect for Config backup - however we haven't seen errors that it fails - but worth looking at I guess.
