Pinned topic performance issues on Grid containers

‏2013-10-29T13:09:35Z |

Hi,

One of our application is timing out while retrieving data from Grid containers. When I checked Grid containers I found following exception in all of the JVMs

 

[10/28/13 23:14:15:789 EDT] 00000249 AlarmThreadMo W   UTLS0008W: The return of alarm thread "Non-deferrable Alarm : 2" (00000008) to the alarm thread pool has been delayed for 16986 milliseconds. This may be preventing normal alarm function within the application server. The alarm listener stack trace is as follows:

We are using extreme scale 8.5.0.1 which is integrated with WAS ND 8.0.0.3 and there are 10 Grid containers. 

I can see a technote with same exception http://www-01.ibm.com/support/docview.wss?uid=swg1PM85931 but that is for nodeagent with the assumption that there are no issues in the environment but we are having issues in our environment. Please advise!

 

Thanks,
