Hab natürlich auch noch woanders gesucht, da das Thema Debugging
aber Neuland für mich ist hab ich vielleicht auch etwas "Berührungsangst"...

Geht so, ich hab meist passende Patchkabel dabei :)
An sowas denkt man ja gar nicht zumal ich der Meinung war, am Hub einen
Uplink-Port zum Providerport zu benutzen, war aber nicht so (Keine Doku)
Also, denn mal los:
root(at)server1 ~> ls -l /var/crash/
total 3463172

.0 ist im Laufenden Betrieb entstanden, .3 ebenfalls.
.1 ist beim Anklemmen des Routers entstanden, dadruch hat sich die
Mac-Adresse des Default-Gateways geändert und ein HOP ist dazu
gekommen. .2 ist beim Einbau des Crossover-Kabels gekommen, da hat
auch noch ein anderer Rechner gebootet.

Wie gesagt ist ein Hardware-Problem auszuschliessen, alles schon getauscht.
Das ganze scheint nur dann vorzukommen, wenn der Kunde seine irgendwo im
Web geklaute PHP-Webmail-Oberläche einsetzt und eine bestimmte Anzahl von
Usern drauf zugreifen. Der Kunde hat ca. 28.000 eMail-Konten auf dem
Rechner.
