Martin Mokry commented on CASSANDRA-4104:
-----------------------------------------
the memory doesn't even fill up. It looks like it just assesses that there is
not enough memory to starts so it just hangs there but doesnt print any message
about it http://pastebin.com/A1pDMWYk . Now I have turned on set -x in
cassandra-env.sh and got some extra messages out of it
http://pastebin.com/S1HxJNLs but still hangs at the end with no apparent system
activity.
> Cassandra appears to hang when JNA enabled and heapsize > free memory

> Key: CASSANDRA-4104
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4104
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.0.8
> Reporter: Joaquin Casares
> Priority: Minor
> Labels: datastax_qa
>
> When JNA is enabled heapsize is larger than free memory, all that is printed
> out is the classpath, then the printouts stop.
> If you hit enter again, you get the commandline, but no Cassandra process is
> running.
> Tested on both OpenJDK and Oracle Java.
