The period is about 40 minutes, and high load state keeps about 10 minutes. CPU status is nearly 100% idle, and no process has high cpu percentages. For example % uptime 7:09AM up 4 days, 11:40, 6 users, load averages: 3.30, 2.52, 1.40 Here is the hardware environment. PC/AT compatible Motherboard Rioworks PDVIA CPU: Pentium III 600MHz x 2 Mem: 128MB x 2 DIMM atapci1: Promise ATA66 controller Fasttrak66 (RAID-1) ahc0: Adaptec 2940A Ultra SCSI adapter vr0: VIA VT3043 Rhine I 10/100BaseTX SVGA: chipset: RIVA 128 I have experienced similar things when I used 3.4-RELEASE, and 3.5-RELEASE. In case of 3.4-RELEASE, the load average kept around 1.0 and never fall down unless reboot. In 3.5-RELEASE, once the load average goes up(not the cause of user or system program), dropped down after a few minutes but it was not periodic. This is similar case to the "Problem report kern/21155 (5.0-current)". >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
