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
s 393216 5432001 --rw------- 70 70 70 70 17 13:46:07 13:46:07

s 393220 5432005 --rw------- 70 70 70 70 17 13:46:07 13:46:07
s 393221 5432006 --rw------- 70 70 70 70 17 13:46:07 13:46:07
s 393222 5432007 --rw------- 70 70 70 70 17 13:46:07 13:46:07

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

Thanks ...
