[webmin-l] kernel: double fault, gdt at dfd3b000 [255 bytes]

[Andrea L. <and...@fr...>]

Hi all,
I had the following problem last night:

Jan 30 21:41:51 srvvmware02 kernel: double fault, gdt at dfd3b000 [255
bytes]
-----
The server is an Opensuse 10.2, kernel 2.6.18.8-0.7-bigsmp 
Webmin version is 1.390
perl -v reports:
This is perl, v5.8.8 built for i586-linux-thread-multi
-----
What make me relate this with webmin is I have scheduled (within webmin) an
automatic modules update at 21.42.

looking at /var/log/messages for other days and for last night looks like
this:

At that point the server was in a strange state: I could ping it, but I
cannot ping any
of the four virtual machines running inside it (it is a vmware server).

I could not shutdown it,nor issue CTRL+ALT+DEL, nor "reboot", also I could
issue command at the console:
I succeded in stopping xinetd i.e.

But I could not issue ifconfig: I had no answer.. but it was not frozen: I
could send this command in background.

Anyway my question is: is there a place where to check if webmin is really
related to this issue ? an update log ?

I scheduled automatical update in order to send me a report: looking at mail
log, almost all days at 21:42:07 
it sends me an email, but not last night, of course.

thanks in advance,
Andrea
