While migrating from 9.2 Stable (9.3Beta3) to 10.0Stable (r267307M) I
noticed that some of the sysctl's that I adjust for tuning purposes
aren't writeable, instead sysctl returns an "Invalid argument".  The two
sysctl's of interest are:
net.flowtable.maxflows and kern.ipc.maxsockets

Would someone advise the new way that these can be adjusted to suite the
purpose of the servers?   There was no mention in src/UPDATING.

Regards, Dewayne.
