Robbie Strickland updated CASSANDRA-10449:
------------------------------------------
Environment: Ubuntu 14.04, AWS (was: Ubuntu 14.04)
Description:
I have a 20-node cluster (i2.4xlarge) with vnodes (default of 256) and
500-700GB per node. SSTable counts are <10 per table. I am attempting to
provision additional nodes, but bootstrapping OOMs every time after about 10
hours with a sudden long GC pause:
{noformat}
INFO [Service Thread] 2015-10-05 23:33:33,373 GCInspector.java:252 - G1 Old
Generation GC in 1586126ms. G1 Old Gen: 49213756976 -> 49072277176;

{noformat}
I have tried increasing max heap to 48G just to get through the bootstrap, to
no avail.
