You speculate that it may be an OS issue, but you fail to specify just what OS you're using. (Your program works on my Ubuntu 8.04 Linux box.)

If it's a Linux or Unix OS then perhaps your account is limited in the number of file locks it is allowed (settable in /etc/security/limit.conf). If you're using SE-linux, that may apply additional restrictions. You can see current locks in /proc/locks.
