[mod_python] "No space left on device:" error when attempting to start httpd2

I'm having a problem running httpd2 with mod_python installed using 
Mandrake 9.2.  I can't really make sense of the error_log.  Here it is:

[Mon May 03 21:13:18 2004] [notice] mod_python: Creating 256 session 
mutexes based on 256 max processes and 0 max threads.
[Mon May 03 21:13:18 2004] [error] (28)No space left on device:

but with diminished ability to process session locks.

problem may be the number of available semaphores, check 'sysctl kernel.sem'

Thanks for any help,
