I am looking for some help/ideas. I am running three containers
on my laptop so I can test some cluster bugs locally. I am fine
with the netty based akka remoting (our default), but I've been
asked to reproduce a bug with the artery remoting.
Every time I start my controllers with artery, they all die with:
ERROR | opendaylight-cluster-data-akka.actor.default-dispatcher-56 |
ActorSystemImpl | 41 -
com.typesafe.akka.slf4j - 2.5.11 | Uncaught error from thread

I'm stuck in the mud on this one so far. I'm trying to tweak the
shared memory setting in the docker run command (to no avail).
The container stats are nowhere near any kind of limit.
It's not happening with netty based.
I've tried both udp and tcp protocols with the same OOM death.
appreciate any ideas or pointers. I'm literally just throwing mud against
the wall at this point hoping something will stick.
TomP tells me it works on his laptop, but he's not using docker/containers,
so that must be a clue.
Thanks,
JamO
