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 cycles,

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.
