[Wylug-discuss] System Crash

[Roy Mac]

On Fedora Core/redhat, I have found that 
 /var/log/messages 
 /var/log/messages.1
 /var/log/messages.2
 .
 .
 .
to be quite useful in resolving problems.  For example, I had a disk drive
acting up.  The SMART on the drive reported this to smartd which in turn,
logged the errors within the /var/log/messages file.  Some kernel panics get
logged.

Given the information provided, I would go examine these files for events
that occurred prior to you noticing this problem.

Mark,

I've seen this sort of thing before, and (when it's locked solid like
this) it's normally eventually traced to a device.  In some cases, it's a
hardware fault, others it's a driver problem (an unhandled condition, for
example).  There are so many possibilities, though, it's hard to know for
sure.

As you say it's run without problem for more than three years then unless
you've done an upgrade recently, I'd suspect hardware degradation and keep
an eye on it.

Mark
