Could somebody please give me a hint on how could I find culprit of this?
what is weird is that kavupdater is just shell script..
I'd be grateful for any help
thanks a lot in advance

RDX: 0000880233743f00.. that certainly will go boom.
That's here in dup_fd():
for (i = open_files; i != 0; i--) {
struct file *f = *old_fds++;
if (f) {
get_file(f);
It's doing that get_file(), grabbing a reference to all open files in a
loop, but old_fds points off into lala land, so I'd say you must have
memory corruption, and open_files is garbage. Seeing "One of our
servers..", operative word being "one", I'd tend to suspect heat or such
given the box exploded in this extremely heavily exercised spot.

yes, that could be. I'll have this box checked, including memtest etc.
thanks a lot for Your time!
