MALLOCFAIL cisco 827

[elias]

Ciao ragazzi,
ho acquistato il router in questione da ebay e finche' navigo su internet non ho alcun problema. Quando invece uso programmi come emule o pnscan la connessione lentamente si congestiona
In consolle visualizzo il seguente errore

Codice: Seleziona tutto

 %SYS-2-MALLOCFAIL: Memory allocation of 32728 bytes failed from 0x800E
3EE8, pool Processor, alignment 0
-Process= "IP Input", ipl= 0, pid= 28

Uso un IOS abbastanza datato: System image file is "flash:c820-osy656i-mz.121-3.XG4.bin"

Qualche idea? Help me pls

A Cisco router that is running Border Gateway Protocol (BGP) might reload under a low memory condition with a bus error at PC bgp_attr2neighboras. Just before the reload, the router displays a message similar to the following:

%SYS-2-MALLOCFAIL: Memory allocation of 32728 bytes failed from 0x602A3FE4, pool Processor, alignment 0 -Process= "BGP Router", ipl= 0, pid= 107

There is no workaround.

Gia'...
avevo googlato un po' trovando qualcosa di simile sul sito ufficiale cisco. Se ho ben capito e' un problema hardware del router e non risolverei nulla neanche aggiornando l'IOS
dico bene?

Sbaglio qualcosa?

Grazie netkiller, con i nuovi time-out ho risolto il problema
Mi sapresti spiegare perche' questo accadeva?

[TheIrish]

succedeva perché la tabella di nat (sh ip nat translation) diventava troppo grande e saturava la ram.

Ancora mi domando come mai i developer della Cisco non abbiano ancora implementato un sistema per il controllo della dimensione dell'heap di modo da non dover far fallire una malloc e magari ritornare un messaggio d'errore più comprensibile. In fondo, un malloc può fallire per decine di motivi diversi!
