What Alex said (except that the script trick doesn't work for
all limits).  We have a code snippet in /etc/init.d/pbs_mom that does:

    # discard any user limits before starting
    ulimit -s unlimited
    ulimit -d unlimited
    echo -n "Starting PBS mom: "
    daemon pbs_mom

Hopefully this fixes the issue.  Let me know if that's the case and I'll
add some documentation somewhere.
