I am running Tectia Server on a Sun 10 box, and I've noticed that few days back my server started to thrown below message for some incoming connections:

Oct  2 18:32:55 SERVERNAME ssh-server-g3: [ID 702911 daemon.notice] 402 Disconnect, Reason: Protocol error, Src IP:, Dst IFace: default, Dst IP:, Src Port: 21511, Dst Port: 22, "Peer sending malformed protocol packets, Remote Disconnect", Session-Id: 19202

The content was obviously masked to hide some internal info. This server of mine handles thousands of connections (about 1.3k users), 4 servants, 256 per each; I've noticed that the error does not happen for all the connections, but I couldn't find any correlation between the ones that raises it.

What is the cause of this error and how can I get rid of it? Thanks.
