> Cassandra Cluster was operating flawessly for around 3 months. Lately I've
> got a critical problem with it - after few hours of running clients are
> disconnected permanently (that may be Datastax C# Driver problem, though),
> however few more hours later (with smaller load), on all 2 nodes there is
> thrown an exception (details in files):
> bq. java.lang.OutOfMemoryError: Java heap space
> Cases description:
> Case 2 (heavy load):
> - 2015-11-26 16:09:40,834 Restarted all nodes in cassandra cluster
> - 2015-11-26 17:03:46,774 First client disconnected permanently
> - 2015-11-26 22:17:02,327 Node shutdown
> Case 3 (unknown load, different node):
> - 2015-11-26 02:19:49,585 Node shutdown (visible only in
> systemlog, I don't know why not in debug log)
> Case 4 (low load):
> - 2015-11-27 13:00:24,994 Node restart
> - 2015-11-27 22:26:56,131 Node shutdown
> Is that a software issue or I am using too weak Amazon instances? If so, how
> can the required amount of memory be calculated?
