Re: Chassis cluster some traffic only seen on secondary / inactive node
Looks like the issue is external to SRX. May be session is reset by server. Is the server accessible locally on those ports?
The session timeout on secondary node is 8 times higher than primary node and the session will not age immediately on secondary node like primary node. If you have access to internal system, try to do packet capture or do it from SRX and analyze it.
