R81 managment server. The connection with server was lost

SPM — Mon, 24 May 2021 14:02:03 GMT

After updating to Jumbo HotFix - General Availability Take 23 ( from Take 13) As long as I hit "Install policy" in Smart Console

The smart console hang for one minute and then displays this

After that Smart Console restarts

I use the latest build of smart consol 81.0.9500.550

During this hang I see a very high CPU usage on management server

I've tried restarting management server, but it didn't help.

It obviously is due to some timeout threshold. Can it be increased and how to do it?

A suggestion...what about if you clone the existing policy and then try install? Does the same issue happen regardless if you click regular install button or if you try one from policy package itself?

Hi @SPM as you stated it might be a timeout issue, is it a heavy policy or first install perhaps?

Please try the following:

Go to SmartConsole installation dir -> Open SmartConsole.exe.config file -> and increase the values of:

KeepAliveSessionTimeoutSeconds

KeepAliveIntervalSeconds

I suggest trying adding a 0, from 10 to 100, and from 30 to 300.

Please update if this lets you install the policy.

Thanks,
Ishai

Thanks for the suggestion and putting into right direction

changing mentioned values did not help

but I've changed SendTimeout to 5 minutes (was 1 minute) in this line:

<CommunicationLayer CloseTimeout="00:01:00" OpenTimeout="00:01:00" ReceiveTimeout="00:01:00" SendTimeout="00:05:00"

And it did help. Thanks again.

it was a lot of changes in the policy, but not so much a lot to suggest that smart console will hit the timeout threshold.
