We are using latest docker release, so I'm not thinking on network issues
Cluster, however, handles a lot of traffic, so perhaps node is "too
busy" to answer within time. Is this possible?
I'll have an eye on syncLimit.
Thanks.
PS: Any other replies are welcome too!

Hello-
It looks like there is a timeout during a ping. This is strange because
pings don't need to transfer much data.
Does the issue always occur with the same learner? Is it possible that
there is a network issue here?
You also may want to consider playing with the syncLimit.
Thanks,
Abe

Ideas?
