[toaster] Strange? behavious on my toaster

[Pelle Lundstr�m]

I have a "fairly" standard toaster the changes i've made are mostly in setting the softlimit and concurancy settings.   There are about 40 users on this server, i use rblsmtpd to filter out some spam and in some cases legit mail that we  get from outsiders sending through open relays.   The strange part in all this is that i some times have a load average above 200, with only about 20 mails in the queue and normal pop/imap traffic, the load average never drops no matter how long i let it sit, if I shut down qmail and restarts it the load average drops to as little as 1 - 3 with no vissible change to the queue or the pop/imap traqffic.   What bothers me furter is that there are alot of zombie processes and lots of defunct perl processes which i believe come from qmail-scanner, i use clam for virus scanning.   does this seem familiar to anyone or does anyone have any tips? noting seems to be wrong when i consult the logs it just seems like a heavy load but i suspect something else is wrong... this is a p3 1000Mhz machine with about 800M RAM and I'm sure that alot less powerfull machine serve alot more traffic.   //pelle
