STAT column (8th, on my machine) may give you some clues - if you see D it's
blocked on something, probably I/O. If you see R, it's in a run queue
waiting for the cpu. Probably not going to see Z, but that's defunct,
meaning the proc is dead and the parent hasn't cleaned it up
yet.</FONT></SPAN></DIV>

Eating Up System Proccesses {Scanned by HJMS}<BR><BR></FONT></DIV><FONT
size=2>Now I have a new problem. When I start MailScanner it seems to tie up
my system so bad that I can't even access web pages. When I look at the system
processes there are a number of MailSacanner processes running eating up the
CPU, some processes as high as 13% and then they go down from there to like 9%
, 7% and so forth. You add them all up and the system is almost at a
standstill. It never used to do this so I don't understand why it is. Any
ideas? <BR><BR>Vernon Webb <BR></BLOCKQUOTE></FONT></BODY></HTML>
