[TriLUG] Non-responsive Linux Box

[Brian Henning]

Some preliminary things...
- How long did you wait for the app to launch?  Switch to a text console 
(Ctrl + Alt + F1...F6), log in and type "uptime" [enter] to see the current 
(1-minute), 5-minute, and 15-minute load averages.  Numbers over 1.0 are 
pretty heavy load (from what I understand, 1.0 represents 100% CPU 
utilization with no waiting-CMIAW).

- How long has the machine been up?  Is it possible that some background or 
periodic task (such as logrotate) has runaway and is chewing up processor 
time?  In that text console, type "top" [enter], then press T to sort by CPU 
time.  If you see anything with more than a few minutes of processor time 
(it will be very obvious, not a small margin), that could be your culprit, 
if the underlying cause is heavy cpu load.

- Any hardware changes, particularly on-the-fly "hot" changes, that could 
have thrown a process for a loop?

Just some thoughts, maybe useful maybe not. :-)

Cheers,
~Brian
