The installation suggests setting: kern.ipc.shmall=32768 kern.ipc.shmmni=1024 kern.ipc.shmseg=1024 The default values on 10.0 are: kern.ipc.shmall: 131072 kern.ipc.shmmni: 192 kern.ipc.shmseg: 128 Suggesting lowering the maximum number of pages available for shared pages doesn't seem sensible. The other default limits look as if they ought to be high enough (kern.ipc.shmseg is the number of shm segments that each process can have open, so should be fine. kern.ipc.shmmni is the total number of shm objects, so might need lowering). If the defaults are too low for KDE to work, please file a bugs against base (and add me to the cc list). It's ludicrous for us to be shipping a default install that doesn't work with modern applications.
My guess is that those were added at a time when the FreeBSD releases we had to support in the ports tree did not all include those limit changes (base r209037 is not in the 8.x branch at least). I have no objection to getting rid of pkg-message altogether.

Back in mid-2012 (ports revisions r297367 and r299321), pkg-message was added to the port suggesting changes to the default shared memory limits in loader.conf(5). Since then, the default limits have been changed and the values suggested by the port are no longer sensible (base r209037, present in all supported FreeBSD releases).
