How do you increase KVA space these days ? I see that in earlier releases you had to edit /sys/conf/ldscript.i386 and /sys/i386/include/pmap.h and do all sorts of crazy stuff.
What is the procedure in 4.5-RELEASE (please say "just change KVA_PAGES=260 to KVA_PAGES=512) That's what you want me to do, right ? Is that all - can it be done just by changing that one value in my kernel config ? Again, thank you Terry for all your help. --PT On Sat, 22 Jun 2002, Terry Lambert wrote: > Patrick Thomas wrote: > > Since all of the things you spoke of basically revolved around "you're > > running out of memory", is it possible or reasonable to think that within > > the space of 1 second, I ran through 1404 megs inactive and 28 megs free > > memory ? > > > > machine is 4.5-RELEASE with 3gigs ram. swap never gets touched, although > > there is in fact 2gigs of swap. `pstat -s` always shows 0% used. > > OK, there's memory, and then there's memory. > > The amount of swap you have, the fact that it's 4.5, and the > amount of RAM you have imply to me that the problem is that > you are out of pmap entries. > > You should up your KVA space to 2G or maybe even 3G; the default > in 4.5 was 1G. > > Basically, I now think that you don't have enough memory to map > how much memory and virtual memory you have. > > Amusingly enough, you might actually have *better* luck with a > lot less swap... > > If your KVA space is already enlarged above the default, then > you can ignore this and just go ahead with the debugging to see > what the wait channels for all the processes that won't run are > stuck at. > > -- Terry > To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
