The following reply was made to PR kern/130274; it has been noted by GNATS. From: Kirk Strauser <kirk@strauser.com> To: bug-followup@FreeBSD.org, kirk@strauser.com Cc: Subject: Re: kern/130274: [sysvipc] Can't shmget() more than 2GB of memory, regardless of kern.ipc.shm{max,all} Date: Thu, 15 Jan 2009 09:37:23 -0600 Anyone? This is a very real problem for people running PostgreSQL on machines with lots of memory. Since PostgreSQL tuning guides tend to recommend using 1/4 of RAM for shared memory, this means that anyone with more than 8GB of RAM is running a suboptimal setup. -- Kirk Strauser
