Problems with 2.2.10 on HPUX 11i

[Connie Starr Fensky]

I accept any and all suggestions, although I've just been told to GO BACK, YOUNG WOMAN! So, I'll be reverting to 2.0.16 tonight. But the top processes are imapd and lmtpd (there are LOTS of lmtps, like 50 or more, and 1500+ imaps)

  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

    I've just upgraded to imap 2.2.10 (with sasl 2.1.10) on my 11i mail server. I did this on a test box, but could not simulate our load (several thousand connections, ~80000 messages delivered a day), and had no troubles. But, of course, putting on the mail server and starting up, performance is abhorrent. I'm running 100% cpu utilization AND memory utilization all of the time, which make the whole system sluggish and the users grumpy. All my fault, and I need to fix it yesterday.  
    I have a pretty basic system--same as can be to my old 2.0.16 one that ran like a dream.Does anyone have any ideas for me--here is configure script:# csf 12/13/04 This is the command I used for configure
