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.
