Hi all,

I host 3 web sites on this machine and all of them
process images. As consequence, the 224MB I have on
this machine is not enough to avoid swamping.

I run only stock NetBSD 3.0 applications
+ BIND9 recompiled from pkgsrc w/o threading support, 
+ Apache 2.2 w/o threading support
+ PHP 4 with GD enabled
+ PostgreSQL 8.1.4

Do you know if there is any 3.0 daemon that is
threaded and need to be reinstalled ?

Ok, if I succeed to build a 3.1 kernel (for the
moment, I have a problem w/ an undefined variable), I
will enable DDB.

As it's my production system, if I can't get this
machine stable, I'll try also to patch the kernel to
reboot the machine if the loading is above 8 ... But
it's a dirty solution.



The misspelling master is on the Web.
