This tells me that perhaps you, as a user aren't able to lock as much
memory as required to startup the job. Can you give it a shot as root?
In BASH you, as root, can adjust your ulimit to unlimited to see if
the problem goes away:
# ulimit -l unlimited
If this works, then you need to adjust /etc/security/limits.conf and
relogin to enable the change.
