i just found my linux6.2 server respond very slow,i use
"top" and found the the load average is about 24,and this
cause my sendmail stop,so i restart sendmail,the system is
ok,and the load average get down,SO,it seems that SENDMAIL
cause such a big load average,but /var/log/maillog say not
first,i want to know if i found the load average is too
large,how to reduce it & how to check why this for??
if you can give me some URL to introduce more about load
average or tuning system working,i will be very glad.
(BTW,i use the "vmstat" to check this server,and,found
the "b" of "procs" is 5,but "r" & "w" is 0,it's sth happen
