Information in this document applies to any platform.
NMS Client locked up for about 10 minutes or more after AMR Pinging 282 meters. Screens wouldn't redraw, couldn't select anything in WorkAgenda, etc.
AMI Pings were just implemented.
Pinging a single meter works fine.
Jconsole showing multiple messages like:
2016-12-01 13:40:08,817 [pool-2-thread-15] WARN com.splwg.oms.client.util.proxy.ProxyInvocationHandler: invoke: ITroubleInfoBean.getCustomersForDevice elapsed: 77410 ms. req: 262 bytes, resp: 443407 bytes
After about 10 minutes, NMS client was working again.
Brought up JConsole on the client. Tried pinging another large batch, about 230 meters.
No indication of extreme CPU or Memory utilization there either. JVM can grow to 2G, but was only using about 1G.
How to Repeat
On a system with large number of records in the AMR_RESPONSES table select a device which has AMI customers in the Viewer and open the AMI Customers page.
Note to long it takes to populate the list of AMI customers for the device.
