semctl(): Invalid argument

What would cause the following?

# psql -U pgsql -l
psql: FATAL:  semctl(327686, 3, SETVAL, 0) failed: Invalid argument

The server is FreeBSD 6.1-PRERELEASE ... there are two jails running on it
... both jails are running PostgreSQL 7.4 ... I have the kernel built with
enough semaphores:

options         SYSVSHM
options         SHMMAXPGS=199608
options         SHMMAX=(SHMMAXPGS*PAGE_SIZE+1)

options         SYSVSEM
options         SEMMNI=4096
options         SEMMNS=8192

options         SYSVMSG                 # SYSV-style message queues

And am definitely not using that many:

(from ipcs -a):
            ID          KEY MODE        OWNER    GROUP    CREATOR  CGROUP          NSEMS OTIME    CTIME

So figure there must be something else that I should be looking at ...

Thanks ...
