} 
} I have a total of 20 CentOS 4.1 systems running on fairly new
} hardware.  About 6 of them are experiencing strange hangs without any
} indication -- nothing in /var/log/messages nor on the console --
} sometime within 10-30 minutes after a reboot.  The systems still
} responds to ping but you can't ssh to it.  At the console, you could
} type "root" at the user prompt but it hangs immediately after hitting
} enter.
} 
} Memory scan of all systems show no error.
} 
} Any idea how to troubleshoot this problem.  The system's not
} responsive to do any troubleshooting and nothing abnormal is in the
} log.
} 
} We running htis kernel: kernel-smp-2.6.9-11.EL.i686.rpm.
} 
} Thanks for any help.

greetings

im quite sure you are most intelligent so you have pry done these things
already..

the first two things that come to mind are... do you have the latest stable
"firmware" on those machines

are they all the same or is there a common denominator besides CentOS 4.1 ?

and have you tried to install the latest kernels and such... there was
recent publishing of them

if they are connected to the internet, unplug for testing??
