Rechner Reboots (neue Erkenntnisse)

Hallo,

weitere Erkenntnisse zum Thema "Rechner bootet selbst wann er will"

Bekannte Fehlermeldungen:

Bisherige Erkenntnisse:

Solange Apache deaktiviert ist läuft das System einwandfrei.
Somit konnte das Fehlerfeld auf das Apache-PHP-Imap System verringert werden.

der Apache läuft mit mod_php4, dies wurde mit IMAP-Unterstützung
kompiliert. Der lokale Mailserver, der vom installierten Webmailer
abgrfragt wird, unterstützt kein IMAP, der PHP-IMAP beherrscht
offensichtlich auch pop3.

Der Fehler tritt ebenso nur bei erhöhter Belastung auf, vielleicht mal
100 User gleichzeitig im System.

Verzeichnis des Webmailers:
