perfSONAR User Q&A and Other Discussion

[Rod James Bio <>]

A work around that worked for me is to set the vars under 
/etc/cassandra/default.conf/cassandra-env.sh to:

MAX_HEAP_SIZE="2048M"
HEAP_NEWSIZE="400M"

I am using an 8core machine with 16GB RAM (12GB Free) BUT a 32-bit 
perfsonar version. So that may be the issue (?).
