Thank you for all your replys and comments.

In 4.6 everything work perfect, so what happen 4.6 - 4.7, it need more mem?

And if I can:
set limit table-entries 500


And with all daemons load in mem I have:

36 processes:  35 idle, 1 on processor
CPU states:  0.5% user,  0.0% nice,  0.0% system,  0.0% interrupt, 99.5% 
idle

Memory: Real: 20M/45M act/tot  Free: 41M  Swap: 0K/161M used/tot

What a perfect world 

So with 41MB free i could load more kernel ...



My other servers: Core 2, i5, i7 with lots of mem (4 or 8 GB).

This and the SUN its to test and see the OpenBSD continue to run happily 
for ever :-) :-)



Thank you for your great effort and work.

pfctl: Cannot allocate memory and spamd-setup -bd

Hi,

I have a server with:

OpenBSD 4.7 (GENERIC) #558: Wed Mar 17 20:46:15 MDT 2010
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC

real mem  = 100233216 (95MB)
avail mem = 87961600 (83MB)


With sendmail and spamd in blacklist (/etc/rc.conf.local):

spamd_flags=-bv   # for normal use:  and see spamd(8)
spamd_black=YES # set to YES to run spamd without greylisting
spamlogd_flags=-i rl0 # use eg. -i interface and see spamlogd(8)




/etc/mail/spamd.conf:

with:china:korea:  it's ok

with:uatraps:china:korea:  -  pfctl: Cannot allocate memory.

or
:nixspam::china:korea: -  pfctl: Cannot allocate memory.

with the shell /usr/libexec/spamd-setup -bd

In OpenBSD 4.6 the same hardware and config ... no problem.

I try several setups: Core2 Duo with 1 GB RAM (the same config) 4.6 and 
4.7, works.


But ... 4.6 and 4.7 with 128MB, 4.7 give the same error: pfctl: Cannot 
allocate memory. 


So I change

set limit tables 1
set limit table-entries 500

in pf.conf, but no luck.

My question is: In this small env. (100 MB - RAM) I need to change the 
Kernel memory or other sysctl value, which one?


I work with OpenBSd for more 10 years Intel, AMD, PPC - Webhosting, 
Servers, Firewalls.


Thank you for your great effort and work.
