Intentional? Known fix? Additional info: sysctl oid mentioned indeed does not exist on 14-STABLE, more oids missing, compare on 13-STABLE % sysctl kern.ipc | wc -l 54 with that on 14-STABLE % sysctl kern.ipc | wc -l 40 One difference - on 13-STABLE, SysV shared memory support is in kernel, in 14-STABLE, sysvshm.ko module is being loaded to provide support, it just looks probably not relevant to the issue I see, I just can't verify it now. At the moment, I can't test it on 15-CURRENT. Regards, Milan
