I have recently noticed a weird thing happening on a server that I have. A few times a day, the drives on my server start thrashing, like they are doing a massive read or write. If I look at TOP while this is happening the only thing that really shows active CPU cycles is sendmail. It uses about 8% of the processing power of the box. After about 10 minutes, the thrashing stops and that sendmail thread stops (user smmsp). During the thrashing there isn't any noticeable performance slowdown. The Box... IBM Netserver 5000 2 GB RAM Dual PIII 550 3x18 gb hot-swap scsi drives (RAID 5) Redhat 9.0 (with all of the latest RedHat up2date updates) Sendmail 8.12.8-6.90 Anyone have any ideas on what my be causing this? -- Jim Streit Partner & Co-Founder NorthLANs Alliance, LLC JimStreit at northlans.com _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
