-------------------------------------------------------------------

So it happened again (not OOM but Gossip pending tasks).
I ran jstack several times. Not sure if that contains a stacktrace devs need.
If that is not enough just let me know how I can make a proper dump.

Stacktraces are attached.

> We have 2 DCs with 3 nodes in each.
> Second DC periodically has 1-2 nodes down.
> Looks like it looses connectivity with another nodes and then Gossiper starts to accumulate
tasks until Cassandra dies with OOM.
