Titolo: Processes CPU

Ciao a tutti,
su un router 827-4V  facendo uno sh processes cpu mi riporta quanto segue :
sh processes cpu
CPU utilization for five seconds: 100%/100%; one minute: 100%; five minutes:
99%
Il router in questo momento non stà facendo traffico ed anche dopo un
riavvio la CPU sembra che lavori al 100%..........Da cosa può dipendere ??
Grazie,
Matador


Se posti l'intero output del comando possiamo vedere quali sono i processi
che "mangiano" la cpu, da li possiamo sperare di capire cosa succede.
Ciao,
        Tosh.

Di seguito l'output del comando "show processes cpu" , è piuttosto lungo e
disordinato.....a me sembra che i processi in percentuale non utilizzino la
CPU :
sh processes cpu
CPU utilization for five seconds: 100%/100%; one minute: 100%; five minutes:
100%

Aggiungo anche un log :
*Mar  1 01:41:46: %CALLTREAT-3-HIGH_CPU_ONE_MIN_LOAD: System experiencing
high cpu utilization over one minute interval.  Processing for callID(42) is
rejected.

Boh .... che i conti sulla somma dei vari processi non tornino mai č
risaputo, probabilmente la lista č sempre incompleta (approfitto per
chiedere se qualcuno ha qualche info in merito), ma non mi era mai capitato
di vedere tutti i processi a zero e la somma a 100.
Io cancellerei la conf, resetterei il router e la rifarei riga per riga.
Se non risolvi cosě prova a cambiare release.
Do per scontato che non hai dei debug in corso, dato che dici di aver spento
e riacceso la macchina.
Ciao,
        Tosh.

Esatto , nessun debug in corso infatti :(
Credo che proverň ad aggiornare l'IOS .
Grazie mille,
Matador

 infatti, genera un NMI che viene processato a livello CPU sul router.
Grazie Andrea ,
č in effetti  un ipotesi  perň dovrei vedere anche molto traffico
sull'ethernet del router  ed invece il traffico č  a zero in quanto questo
router viene utilizzato solo per il VoIP e in LAN hanno un altro 827 che
utilizzano per la navigazione Internet....Naturalmente se ci fosse molto
traffico di broadcast anche l'827 VoIP ne sarebbe coinvolto ma dovrei vedere
il traffico sull' Ethernet .
Grazie ,
Matador

Solo per ringraziare tutti quelli che hanno risposto al mio post e per
informarvi che aggiornando l'IOS il problema del carico della CPU si č
risolto  .
Grazie ancora ,
