System: NetBSD proxy2.clinet.fi 1.3_ALPHA NetBSD 1.3_ALPHA (CLINETALPHA) #17: Thu Oct 23 21:32:05 EEST 1997 email@example.com:/usr/src/sys/arch/alpha/compile/CLINETALPHA alpha
512M, 5 wide-SCSI disks. Intended to be a proxy server
When trying to up maxusers in kernel config (plain GENERIC config),
kernel breaks up. At 32 it panics with
: can't get KPT page
(before reporting memory sizes and such)
at 64 (and up) kernel reports memory sizes and locks up.
Experimenting with kernel parameters I noticed that I can up NMBCLUSTERS
but making NPROC 2048 causes same deadlock.
I hope to get around this for a proxy server as I am able to get more
NMBCLUSTERS and max *size limits, which probably is the primary problem
with a proxy server. For other users one probably wants larger process
Modify GENERIC with maxusers larger than 16.
