You can find my strace with timestamp on the below link. http://pastebin.com/m2942fbdd My /home partition using san storage with ocfs filesystem. I have configured mailarchivel, where in which a copy of all mails will sent to one mailbox. In the archive mailbox using sieve script i am sorting the mail according to username, year, month and delivering it. When ever i am removing my max procs option limit from 4 to default in postfix. System cpu usage become high. Then i have to put the limit again to make my cpu usage go down. Rgds, Aravind
