ws_mux errors in /var/log/messages

[lucafabbri365]

Hello,
we have R80.20 version in production: two physical Security Gateways nodes in cluster (Open Server) and on virtual Management.

I noticed /var/log/messages contains these entries:

Are you actually experiencing any issues or you just want to know what the messages mean?

Hello,

I don't experience any (visible) issue, apparently; I just want to know what the messages mean.
I made a search on Internet for keyword "ws_mux errors" but I didn't find anything related, so I asked here.

Bye,
Luca

I would involve TAC to answer this question.
