[APACHE] blocage du serveur sans message clair

Sous XP SP2, j'utilise APACHE 1.3.33 et MYSQL4.1, PHP5.1.2
Pas de problème particulier dans un usage INTRANET ....
Depuis quelques mois, l'usage de COM ajoute une souplesse dans les liens avec EXCEL.... mais !
Depuis 2 ou 3 jours, des blocages innopinés (sans message dans error.log) m'obligent à un arrêt brutal de ma config !
Seuls les messages dans le répertoire temporaire me font penser à un problème sur ma config .... dont voici un exemple ci-dessous
