Aker" Cc: user-mode-linux-devel@lists.sourceforge.net, Blaisorblade I have skas3-v8 host servers with model 4 processes and good (100+ day) uptimes. The host server I had issues with (host38) got converted to Xen and is still having problems. I am seeing issues with host34 that require the odd restart. That server runs the same CPU model and kernel code as other servers of mine with good uptime. My conclusion is that I must be seeing hardware issues rather than a skas bug. - Peter # for ((i=34;i<41;i++)); do echo host$i $(ssh host$i 'echo $(cat /proc/cpuinfo | grep model | grep -v name | head -n 1) $(uname -r) $(uptime)'); done host34 model : 2 2.6.11.10-skas3-v8 21:52:37 up 15:19, 0 users, load average: 1.64, 1.60, 1.32 host35 model : 4 2.6.11.7-skas3-v8 21:49:21 up 42 days, 12:15, 0 users, load average: 13.72, 9.66, 5.21 host36 model : 4 2.6.11.12-skas3-v8.2 21:49:23 up 61 days, 0 min, 0 users, load average: 1.26, 1.44, 1.78 host37 model : 4 2.6.11.7-skas3-v8 21:49:25 up 121 days, 9:48, 0 users, load average: 0.91, 1.04, 1.14 host38 model : 2 2.6.11.12-xen0 21:49:26 up 7 days, 13:28, 0 users, load average: 0.02, 0.05, 0.01 host39 model : 4 2.6.11.7-skas3-v8 21:49:28 up 106 days, 2:46, 0 users, load average: 0.59, 0.65, 0.70 host40 model : 4 2.6.11.7-skas3-v8 21:49:39 up 121 days, 9:47, 0 users, load average: 0.27, 0.43, 0.47 Christopher S.
