J2EE Engine Restarts Automatically

[Former Member]

Hi all,

We have a clustered environment with 2 J2EE dispatchers and 2 server nodes per J2EE dispatchers. Whenever a server node has a problem with the Messaging Service all the J2EE server nodes restart.

The following is part of the std_server log that seems to have problem

[Framework -> criticalShutdown] Missed broadcast due to network problems. Restart is required (advanced Reconnect)

[Framework -> criticalShutdown] Exiting Listener Loop. This requires a restart of the node. Possible reason is an interrupted
reconnect session to the message server.

Anyone familiar with "Missed broadcast due to network problems. Restart is required".

Can I change any parameter to increase the MsSSuspendCheck time to more than 40s.

Hi Kummari,

Thanks for replying.

I have checked SysInfo; it look OK.

If license was an issue then J2EE would restart after 30min (?) and logs would mention the cause clearly.

My J2EE engine runs for days and restarts occasionally.

regards,

Roshni

Hi Roshini,

Did you get any solution for above problem?

Interestingly we are also getting the same error and our system configuration is same as yours.

Thanks

We have upgraded the JDK to the latest version and started using one server node per dispatcher. The problem doesn't seem to appear anymore.

Also, this problem is unlikely to occur on 7.1 eHP1. Even if the messaging service is killed, the server node continues to run. It won't accept new requests, but at least server node doesn't go down.

Hi Roshni,

I have discover this problem today!

From time to time (not during the start process of the Was Java) , II have got the same error message.

In my /j2ee/cluster/server0/log/system/server.0.log. I see those message "Critical shutdown was invoked. Reason is: Missed broadcast due to network problems. Restart is required (advanced Reconnect) , Fatal , /System/Server/Critical , com.sap.engine.core.Framework "

And my Was java server node is restarted

I am in J2EE 7.0 SP15 on Solaris Server

I have one JAVA CI and 4 JAVA Application server on 4 different hardware server.

If you have any clue, please let me know.

Regards

I have already checked OSS note 920889.

It did not help me.
