Oh, is this on HPUX ? HPUX is one of the insane
systems that has a hard coded limit on the number
of allowable fcntl locks. You have to change a
kernel tunable and reboot to fix this.

If it's running out of fcntl locks on HPUX this
is a known HPUX bug - we tell people to up the
number of allowable locks and reboot.
