Re: Help, I may be losing my mind ( Shared memory )

What OS and OS Version? Find out from the SA (if it isn't you) what the SHM* values are. Maybe the values for the MIN values are set extremely high? Also what is the MAX value? If set to 2.1G then that would be why it was capped like it was. On 8/21/06, Floyd Wellershaus <fwellers@yahoo.com> wrote: > > > I think I'm going crazy.
