OutOfMemory log in Cassandra

[Xu Renjie]

Hi, all
   I have a problem about the log. I have set the CASSANDRA_HEAPDUMP_DIR in
the cassandra-env.in file to some path to store the dump file
when OutOfMemory exception happens. But after out of memory happens(I judge
it from the /var/log/messages which says "kernel: out of memory:
kill process XXXX), there is no dump file generated in that path. Is this
because kernel kill the jvm first so no OutOfMemory exception thrown or
what? I am new to linux. Thanks in advance.
