I did a quick search on site looking for the above in BES 5.0/mr4 router logs; we seem to be getting this on 7 BES no matter the load on it.
Is there a way to resolve this issue other than the standard cryptic answers? I have BES in different locations using different routers/connections/etc and they all have the same issue.
I already did the RIM (KB article) troubleshooting and found nothing... Please shed some light on this perplexing issue.
I also have been experiencing this issue and after extensive troubleshooting/support calls to RIM I have deduced it is just a bug. We are running our 2 BES's in a vSphere 4i environment and have had it since day one of the upgrade.
It does not appear to have any negative effects on the performance of the server.
