Service/connection disconnected after "upgrade" to R60

[NickBrandson]

dear guru,

Have you ever encountered session/connection disconnected after switching to R60 firewall cluster (A-S) on SecurePlatform?
It seems there is some changes hv been made to the kernal, and terminal some tcp session like telnet, remote desktop connection and even the SmartDashboard. we are connecting to the SmartCtr behind the R60 firewall remotely. This does not happen before on R55 Cluster on Windows.

All the latest HFA (HFA04) has been installed on SC & gateways.

Any ideas would be appreciated.
Thanks,
Nick

Do you mean disconnect after an hour's idle time? Or shorter than that?

Is the cluster maybe flapping? Check your logs to see if you've got active/standby switching frequently. Related to that, check that they're synchronising properly.

We ever doubted there's some problem with the cluster, sync issue or even the NIC card, the sync interface is connected to hub (does not support multicast)

The cluster seems normal, and we even tried to switch off one of the gateway and it still happened.

It seems there's some setting has been change on the kernal for the timeout value, we are going to take a look of the packets of the source machine and see if there's a reset packet by the firewall or something.

We have configured the tcptimeout value in Global properties, some improvements, but it could not solve.
