------------------------------------------
bq. I can make the change but i dont have the HW to test it out
I can test it.
bq. do we want different default env vars for server and client?
>From what it seems, CLIENT only refers to zkCli. We do not need a huge heap
>for that. Are you thinking of ZOOKEEPER_CLIENT_HEAPSIZE and
>ZOOKEEPER_SERVER_HEAPSIZE?
> zookeeper should set a default value for SERVER_JVMFLAGS and CLIENT_JVMFLAGS
> so that memory usage is controlled

> We noticed this with jdk 1.6 where if no heap size is set the process takes
> up to 1/4 of mem available on the machine.
