RE: CustomLog to a pipe question

Thank you very much for advice. I did as y suggested but still have some
problems.
I have three web servers and one of them is writing log.
On each server I have /etc/spread.conf

> Spread_Segment  192.168.123.95:4803 {
>         srva 192.168.123.69
>         srvb 192.168.123.71
>         srvc 192.168.123.70
> }
> EventLogFile = testlog.out
> DaemonUser = spread
> DaemonGroup = spread

on each server I run: spread &
and on each server I have in httpd.conf
        <IfModule mod_log_spread.c>
         SpreadDaemon 4803
         CustomLog $www virtualhosts
        </IfModule>
But still on the weakest server from time to time I get
[Fri Nov 21 21:58:54 2003] [error] (2)No such file or directory: Could not
connect to spread  with private_name ap27959. Error -6
[Fri Nov 21 21:58:54 2003] [error] (2)No such file or directory: Could not
connect to spread  with private_name ap27958. Error -6
When I run spuser and join www I see some logs coming in.
When doing netstat -a I see that it's using unix socket to connect to
spread:
unix  3      [ ]         STREAM     CONNECTED     143538335 /tmp/4803
and I have average 35 httpd processes running now and I have same count of
those:

# ps aux|grep "/usr/sbin/httpd"|wc -l
     35
# netstat -a|grep "/tmp/4803"|wc -l
     33
# uptime
 10:05pm  up 139 days,  5:34,  4 users,  load average: 0.27, 0.21, 0.34
# cat /proc/cpuinfo |grep MHz
cpu MHz         : 549.849
# ss|grep  requests/sec
   1.3 requests/sec - 29.6 kB/second - 22.7 kB/request

Sometimes httpd process count jumps to 100 and I would like it to handle
that as well.
I would really appreciate if somebody could help me.

Sounds like he is overconnecting to a single daemon (as is described in
README.spread in m_l_s sources).  It's not advisable to run a single
daemon and have everyone connect to it.  Much better to have every host
run their own daemon, all belonging to the same spread ring.
