Memcached server won't start after install on RHEL6

Installed the Couchbase Server 2.2 via RHEL6 64-bit RPMS, and everything went fine during the RPM install, and the web-based setup wizard.

After the setup was complete, the server was marked as down (though the web page is still accessible). In the log view, the following is the error that seems to be showing up over and over again.

Port server memcached on node ‘babysitter_of_ns_1@’ exited with status 71. Restarting. Messages: Mon Mar 31 17:28:16.824570 EDT 3: failed to ensure corefile creation

Also looking in the /opt/couchbase/var/lib/couchbase/logs directory, there is a bunch of memcached.X files being created with errors about unable to create core file.

It appears that the memcached server that listend on 11211 isn’t starting, but the logs are so cryptic, it is not clear as to what might be the problem.

Anyone have any ideas?
