zonemta container bursts on the CPU every time it retries, and memory allocated to the container grows by 100-300M every restart (indefinitely, stopped it at ~20G)

Using default generated config, with env HOSTNAMES=sub.domain.tld (removed [], as =[sub.domain.tld] didn't work.

Mongo seems to be getting connections:

I also have this issue, any information on it would be appreciated

turning off mongo net compression helps with the load if it's a big-ish environment
config file (github doesn't let me align it properly):
net: port: 27017 bindIp: localhost compression: compressors: disabled
