Subject Re: java.lang.OutOfMemoryError: Java heap space

The short-term fix is probably to try increasing heap space (in
cassandra-env.sh). 8GB in the most standard but more may help in some
circumstances.

That said, your logs are pointing to a number of other issues which won’t
be helping and probably need to be fixed for long-term stability:
- swap enabled ( Cassandra server running in degraded mode. Is swap
disabled? : false,  Address space adequate? : true,  nofile limit adequate?
: true, nproc limit adequate? : true)
- low disk space ( Only 36948 MB free across all data volumes. Consider
adding more capacity to your cluster or removing obsolete snapshots)
- large partitions ( Writing large partition feed/messages:MANAGER:0
(175811867 bytes))

Cheers
Ben
