Here it starts again :( The machine is up for a little bit more that 1 day [root@tux infocast]# uptime 12:04:42 up 1 day, 3:53, 12 users, load average: 0.18, 0.37, 0.48
I feel it because the machine seems to be slower when it happens, probably because it does have less and less memory available...
And here what the slabtop output monitoring reports : Thu Jul 30 11:49:04 CEST 2009 task_delay_info 3292 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:50:04 CEST 2009 task_delay_info 3292 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:51:05 CEST 2009 task_delay_info 3292 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:52:05 CEST 2009 task_delay_info 3292 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:53:05 CEST 2009 task_delay_info 3292 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:54:05 CEST 2009 task_delay_info 3289 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:55:11 CEST 2009 task_delay_info 3309 3312 112 36 1 : tunables 0 0 0 : slabdata 92 92 0 Thu Jul 30 11:56:15 CEST 2009 task_delay_info 16631 16632 112 36 1 : tunables 0 0 0 : slabdata 462 462 0 Thu Jul 30 11:57:15 CEST 2009 task_delay_info 58860 58860 112 36 1 : tunables 0 0 0 : slabdata 1635 1635 0 Thu Jul 30 11:58:15 CEST 2009 task_delay_info 98422 98424 112 36 1 : tunables 0 0 0 : slabdata 2734 2734 0 Thu Jul 30 11:59:15 CEST 2009 task_delay_info 138023 138024 112 36 1 : tunables 0 0 0 : slabdata 3834 3834 0 Thu Jul 30 12:00:15 CEST 2009 task_delay_info 177587 177588 112 36 1 : tunables 0 0 0 : slabdata 4933 4933 0 Thu Jul 30 12:01:16 CEST 2009 task_delay_info 217151 217152 112 36 1 : tunables 0 0 0 : slabdata 6032 6032 0 Thu Jul 30 12:02:17 CEST 2009 task_delay_info 256715 256716 112 36 1 : tunables 0 0 0 : slabdata 7131 7131 0 Thu Jul 30 12:03:17 CEST 2009 task_delay_info 296316 296316 112 36 1 : tunables 0 0 0 : slabdata 8231 8231 0
