Is the CPU maxing out on the UE with the poll ? or maybe ICMP redirect
Hell ?

So were you getting a 10 second long drop in traffic once per minute?
Is your ICMP/SNMP poller traffic hitting a dedicated bearer or default
bearer? I think the AMBR on a dedicated bearer is not currently
enforced, so if there's a dedicated bearer with higher priority than
the default bearer, and if the SNMP traffic is significant enough,
then one or two low MCS UE could drag down a whole eNB until the
polling was completed.
Just a theory.

Have you tried shutting off only the SNMP polling for a few

This is why I said I've found the source, but not yet the cause. I'm
going to see if I can isolate SNMP from ICMP, depending on the
poller's decision tree.
I'm not eliminating some kind of arp bottleneck either until I've
sniffed @ the EPC.
