Problems with 2.2.10 on HPUX 11i

[John Wade]

Hi Connie,

I know this falls in the obvious category and you probably already
checked this, but what log level are you using?  (/etc/syslog.conf)  At
debug, we have found that at our moderate load (300 simultaneous users)
on linux, the CPU usage of syslogd is very high.

What does top or (glance if you have it) show as the processes using the
CPU?

Hope this helps,
John
