OK I got the response to one of my questions. In= the script /etc/init.d/cassandra we set the path for the heap dump by defa= ult in the cassandra_home.

Now the thing I don't understan= d is, why do the dumps are located by the file set by /etc/init.d/cassandr= a and not by the=C2=A0 conf file cassandra-env.sh?

Anyone any = idea?

This op= tion is defined in cassandra-env.sh

if [ "x$CASSANDRA_HEAPDUMP_= DIR" !=3D "x" ]; then
=C2=A0=C2=A0=C2=A0 JVM_OPTS=3D"= ;$JVM_OPTS -XX:HeapDumpPath=3D$CASSANDRA_HEAPDUMP_DIR/cassandra-`date = +%s`-pid$$.hprof"
fi
=C2=A0and we defined before the value of CASSANDRA_HEAPDUMP_DIR before to
/cass= andra/dumps/

It is seems that cassandra= does not care about the conf in cassandra-env.sh and he only takes in acco= unt the last set for HeapDumpPath /var/lib/cassandra/java_147546128= 6.hprof

This causes problems when we ha= ve to dump the heap because cassandra uses the disk not suitable to do it.<= br>
Is=C2=A0 XX:HeapDumpPath set in anot= her place/file that I dont know?
