i saw that my mail hub decided to start showing this now too.. first it was my web server. seems to be somewhat related to uptime. my webserver started it a few months ago (it has about 390 days uptime) and my mailserver just recently (it has about 249 days uptime)
seems to be a kernel bug but wanted to confirm ...i read a thread on the kernel list but only saw discussion on what could of been a bug. both systems running 2.2.19 now that i think about it it is probably the cause of the inverse results ive been getting for uptime, cpu load and memory usage from mrtg from yet another server that recently passed the 220-230 day uptime. a couple weeks ago the mrtg graphs for a mailserver completly inversed out of nowhere(nothing changed on the system). very odd! here is the error: mail:~# uptime Unknown HZ value! (0) Assume 100. 1:31pm up 249 days, 2:39, 2 users, load average: 0.10, 0.03, 0.01 Linux mail 2.2.19 #1 SMP Wed Mar 28 10:23:03 PST 2001 i686 unknown [EMAIL PROTECTED]:~$ uptime Unknown HZ value! (3) Assume 100. 1:33pm up 256 days, 18:02, 1 user, load average: 0.06, 0.03, 0.01 on the kernel mailing list i saw it seemed to be specifically related to SMP systems and all 3 that are affected are dual proc. yep that is the cause! i just checked my mrtg graphs for the mail hub and now they are inversed. the thread mentioned something about idle time looping..and it seems it did, from procinfo on the mail server: user : 9d 3:18:56.01 0.0% page in : 54302702 disk 1: 13365391r114547578wnice : 1d 7:31:10.76 0.0% page out:324831048 disk 2: 8805788r47393718w system: 19d 9:21:42.79 0.0% swap in : 109345 idle : 483d 15:57:35.24 0.0% swap out: 12434 uptime: 256d 18:04:42.39 context :1562566116 damnit! maybe time to post to the kernel list .. never thought there would be a downside to uptime :) [EMAIL PROTECTED] nate
