Weird message in dmesg
Hello all, I have a strange warning message in dmesg: warning: total configured swap (15728640 pages) exceeds maximum recommended amount (22369984 pages). warning: increase kern.maxswzone or reduce amount of swap. (The configured pages are actually less than maximum) The value of kern.maxswzone in /boot/loader.conf is: kern.maxswzone=201326592 Anyone knows what's going on?! /OriS ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

I think there is a typo. Should be:

Re: Weird message in dmesg
Yup, that seems to be the issue...
I kept bumping up the value of kern.maxswzone until the warning disappeared.
Should be incorporated into sources I guess.
Thanks! :)

Correct. The theoretical maximum is maxpages, but due to fragmentation,
you can run out of space well before that.

Re: Weird message in dmesg
Yep, this also causes the warning not to be emitted at all. Well, maybe it'd be a good idea to set it to 0 on amd64 systems for amd64-RELEASE's.

It is the hardcoded default for both i386 and amd64 in 9.1 and earlier releases. I have not merged the new limits and warning code yet.
