I am having a problem with a new server that I am setting up to host my UseNet news and email. Machine: 1.26GHz 512MB/L1 Cache 768MB PC133 Memory 4x60GB UDMA100 IDE Drives 4x36GB 160MBit SCSI Drives OS: 5.0-CURRENT (yes I know, but I have been CURRENT since 386bsd 0.1) Software: INN 2.3.3 Sendmail w/amavisd milter ipop3d This machine has been running for about 2 months on CURRENT with no problems, but I recently upgraded the CPU from an 866 to the new one. At that time, I also planned to replace the motherboard with a new Intel SAI2 dual processor board, add a 2nd processor and drop in 3x512MB ECC Registered DIMMs. So I built and installed a more current CURRENT and added SMP to the config for my kernel. The motherboard was defective, so I put back in the original board and memory chips, while I wait for the replacement board. The 2nd night after the build was done, I started having memory/swap/wired problems. I rebuilt the kernel for UP operation, but the problems have not gone away. Machine averages about 95% idle all day except during news expiration. For the first day, it averages around 45M wired. 'inn' process is about 137MB RSS. During expiration there is an understandable spike in CPU and Swap activity. 'expire' process is about 259MB RSS. When the expiration completes there is about 254MB still wired. The second night it goes to 500+MB wired and the system never finishes expiration before I get a call that email is down. I have actually gone out and killed every process running on the machine that I can (including inetd, syslogd, cron, sshd, sendmail and inn). The wired memory is never released until I reboot the machine. Any ideas (other than going to STABLE :)? - brian +-----------------------------------+------------------------------------------+ He rides a cycle of mighty days, and \ Wm Brian and Lori McCane represents the last great schizm among\ McCane Consulting the gods.
