Re: computer lockup


I've seen similar lockups on an HP dual-Xeon running Fedora 9.  The
machine is running LDM on a pared-down version of the CONDUIT data,
but is not generating graphics using GEMPAK from any of those LDM
processes.  GEMPAK is installed and used separately, and I have never
considered it to be part of the problem (though I could be wrong).  I
see the same behavior with crons not running and the machine locking
up.  This occurs maybe once every one or two months and seems to be
preceded by the machine responding really slowly.  Personally, I have
felt that it is a kernel bug somewhere, but no kernel upgrades have
ever fixed it, I am now running 2.4.20-37.9.

I too would love to hear any solutions.

Hello All,
I'm running a Dell Xeon processor with RedHat enterprise linux v. 3
installed. This system is used only for retriving data from ldm (6.1.0),
creating images with gempak (5.7.3) and displaying these images over the
web via apache. (also 1 java script).  Recently, the computer has been
locking up.  The symptoms are simply the computer becomes unreachable.
Even locally, if I go to the computer, it does not respond.  I am forced
then to cycle the power in order to get the system to once again respond.
Checking the system log files hasn't shown anything (at least to me)
except that when this lockup occurs, the cron does not run (usually).  If
anyone has any ideas as to what may be occuring it would be GREATLY
