Hi guys,
I'm feeling a little out of my depth here on this one. This box was built two Autumns ago (1998) and has only had a monitor change since. Using RH6.0.
Tonight, on two seperate occassions, between 30 seconds and one minute into my dialup Internet connection, my machine has totally locked up.
The only commonality has been the dialup and corresponding disk activity (sendmail and fetchnews kicking in).
I have had an in-between dialup connection that stayed up fine.
The screen freezes. No mouse, no keyboard. The four consoles do not respond. No beeps occur on keyboard buffer overflow as you'd normally expect. The modem stays on-line, but Rx/Tx lights go dead. The hard disk stops rattling completely (I can normally hear it all the time).
I have 64MB RAM, 128MB swap. gkrellm shows swap to be at or less than 1/4 used, RAM between half and 3/4 used. I run GNOME 1.0.53 and E 0.16 and on both occassions had two Eterms up.
Absolutely nothing out of the normal, bar having 'daytime' uncommented in /etc/services (I was trying out a networking code sample from a book). I have now commented it back out.
I was not accessing audio/cdrom devices, nor floppy (LS-120).
I am using kernel 2.2.12, and have been for smoe time.
the best thing I can suggest is to upgrade to the latest stable kernel and remake your swap file if you think it is corrupt, I have had a corrupt swap file before and it does do weird things! One more thing... UPDATES !!!.. there have been a lot of security updates since 6.0 was released, I'm not sure if any of these allow remote lockups?? but if your not sure then upgrade all the necessary packages in the redhat updates directory on your local mirror...
this is one thing I will shout from the highest rooftop to to everybody out there who has machines which are online in anyway, updates updates and updates;)..
give these a go and see what happens

The only thing that comes to mind is possibly swapfile corruption, but I don't even know if it's possible with Linux/ext2 or whatever.
Unless the problem is an apparently random hardware fault. I must admit since using GNOME again this past few days memory has been a little lacking.
Ideas?
