Ping Failing from collector to device and back?

I am pleased to announce that LM has (after nearly 5 years of back-and-forth -- my first attempt to get this addressed was in June 2018) finally has fixed both the SNMP and ping issues impacted by intermediate firewall session invalidation -- update from support last week:

Our development team has acknowledged the issues you outlined with Ping. Currently the behavior is to have cached sessions for ICMP ping and then reuse them, only refreshing the cache on sbproxy restart. An alternative has been in development and will be fixed in the next EA release. Similar issues with SNMP have been addressed already in EA 34.100.

Hopefully this is actually the case, but if so it will be very nice to tell our clients this longtime bug has finally been quashed.
