[squid-users] FreeBSD, 4GB of Ram, Making Squid USE it!

[Gaylord Van Brocklin]

My Dual 2.0GHz Xeon w/ 2GB of RAM boxes just got upgraded to Dual 
2.8GHz Xeons with 4GB of RAM.  The boxes are running FreeBSD 
4.10-STABLE (cvs updated and rebuilt as of yesterday).

My previous kernel was set with MAXDSIZ="(1843*1024*1024)", Squid sat 
at around 1700MB of memory utilization and I never had any stability 
issues.

I am trying to recompile the kernel with MAXDSIZ="(3072*1024*1024)", 
but am getting mmap errors when I reboot.  I read a TON of stuff about 
FreeBSD, 4GB of memory, KVM_PAGES, and kernel tuning issues, so I tried 
setting MAXDSIZ to 2048 which allowed the machine to boot, but services 
wouldn't start due to memory/threading issues.

Why can't I tune this box past 1.8GB of memory for Squid?  Do I need to 
go to 5.3-RELEASE?  How are you guys getting Squid to eat up more than 
2 gigs of memory?

Thanks!
