I just got lots and lots of this:
    kern.ipc.maxpipekva exceeded; see tuning(7)

However, tuning(7) on my system has no information about this tunable 
whatsoever.

anglepoise:~ % uname -a
FreeBSD anglepoise.lon.incunabulum.net 7.1-PRERELEASE FreeBSD 
7.1-PRERELEASE #3: Tue Nov  4 15:40:44 GMT 2008     
root@anglepoise.lon.incunabulum.net:/home/obj/usr/src/sys/ANGLEPOISE7  amd64
anglepoise:~ % sysctl kern.ipc.maxpipekva
kern.ipc.maxpipekva: 20971520

I was running a couple of copies of "synergys" at the time. After 
killing them, all seems fine,  however this was causing most binaries on 
the system to error out with ENOMEM.

Any ideas?
