Comment 1 Bill Nottingham 2000-07-12 16:17:57 UTC

No matter what slocate is doing, it shouldn't cause a kernel oops;
reassigning to kernel.

Comment 2 Nicolas CROISET 2000-07-15 07:29:21 UTC

Perhaps these informations will help you.

on this machine we have two PPP connections one named ppp0 and the other one ppp1, in the options we have NODEFAULTROUTE with PAP 
protocol.

Then, we make every 5 minutes an addroute default to ppp0 then we delete it. we make a default route to PPP1 and then we delete it.

This kernel panic was done when the ppp0 or ppp1 was killed because the connection was loss. When we verify if the connection is loss we del the 
default route manually, because this route was not del automatically.

This night we had excactly the same problem at the same time but we had stop slocate two days before this new crash.

Comment 3 Nicolas CROISET 2000-07-25 13:01:08 UTC

Hello,

I have a second kernel panic when I make the command route :

This kernel panic was done with the last kernel : 2.2.16-3 in redhat 6.2

Bye.

Comment 4 Alan Cox 2000-08-22 16:25:25 UTC

Please run a memory tester on that box firstly

Comment 5 Nicolas CROISET 2000-10-12 09:40:38 UTC

It was a problem with the RAM.
