Have there also been changes to the semaphore usage over the last 10
days? A February 15th snapshot is fine on my systems, as long as I
apply the patches that appeared here yesterday to get Kerberos going,
but after 'cvs update' yesterday (February 23rd), the postmaster is
refusing to start, claiming that semget() failed to allocate a block
of 16 semaphores. The default maximum here is 60 semaphores, so I
guess it must have allocated at least 44 of them before the failure.
This is under NetBSD/i386-1.3I.
