DLLHOST.EXE

Bonjour

J'ai un serveur web sous Windows 2000 Server et IIS 5.0
Depuis 48 heures environ... j'ai un processus DLLHOST.EXE qui prend toutes
ressources de mon système. Du coup tous mes sites sont super lents
Le processus tourne sous le nom de IWAN_...
Cela dure dure environ 2 ou 3 mn avant de revenir à la normale. Puis ça
recommence 5 mn aprés. Ainsi de suite. J'ai 8 processus DLLHOST.EXE qui
tourne sous le user IWAN_ et 1 qui tourne sous le nom de SYSTEM.

Je n'ai trouvé que trés peu d'infos. J'en appelle à vos connaissances.

Merci.
Jean-Paul.

Bonjour

Google :

COM+ contrôlent les processus présent dans le serveur IIS et est
utilisé par beaucoup de programmes. DLLHOST charge par exemple le
RUNTIME .NT.
Il est possible d’avoir plusieurs instances du processus DLLHOST.

Non mais ça je sais ce qu'est DLLHOST.EXE, mais ça résoud pas mon pb
si joint le log obtenu avec iisstate

Opened log file 'C:iisstateoutputIISState-2016.log'

Bonjour

J'ai un serveur web sous Windows 2000 Server et IIS 5.0
Depuis 48 heures environ... j'ai un processus DLLHOST.EXE qui prend toutes
ressources de mon système. Du coup tous mes sites sont super lents
Le processus tourne sous le nom de IWAN_...
Cela dure dure environ 2 ou 3 mn avant de revenir à la normale. Puis ça
recommence 5 mn aprés. Ainsi de suite. J'ai 8 processus DLLHOST.EXE qui
tourne sous le user IWAN_ et 1 qui tourne sous le nom de SYSTEM.

Je n'ai trouvé que trés peu d'infos. J'en appelle à vos connaissances.

Merci.
Jean-Paul.

Bonjour

Google :

COM+ contrôlent les processus présent dans le serveur IIS et est
utilisé par beaucoup de programmes. DLLHOST charge par exemple le
RUNTIME .NT.
Il est possible d’avoir plusieurs instances du processus DLLHOST.
