Lige nogen tig du bør holde øje med på maskiner er hvad siger "free"lige før den går ned. Nogen sjove ting i "top" og er der noget mærkeligved en "ps ax".


1. Prøv at slå quota's fra og se om problemet stadig er der.
2. Prøv at skift ram'en i kassen.

3. Kør en fsck på din ext3 partition, ext3 er ikke alt for stabilt hvisens metadata ikke lige er som den forventer det.4. Prøv at compile din egne kerne, den RedHat lever fungere ikke altidlige som den skal på alt hardware.

Når du har prøvet alt det burde du være tættere på en løsning, det kanvære mange ting, jeg har selv haft en del problemer med ext3, så jegholder mig til reiserfs, den har jo så også den fordel at den er en delhurtigere til små filer og det passer jo fint med Maildirs ogcourier-imap. Jeg ved ikke hvad for en pop3 server du bruge med, men foreksempel qpopper og gamle udgaver af uw-imap har haft den dålige vane atloade hele mailbox'en ind i hukommelsen, hvilket gør ondt når man har3000 brugere og Linux kan godt opføre sig "sjovt" når den løber tør forhukommelse. Hvis det er sådan noget du er ude i, kan jeg godt anbefaledig courier-imap i selvskab med postfix, det er meget nemt at installereog sætte op, og er efter min erfaring en del mindre resurse krævende endfor eksempel sendmail + uw-imap/qpopper.

Hej

Jeg har en RedHat 7.3 kørende med sendmail som mailserver, den håndtere mail
for ca. 3000 brugere og den har problemer med at den går ned ret ofte.
Det der sker er at det overhovedet ikke er muligt at komme i kontakt med den,
hverken via ssh, pop3, smtp eller web.
Det kan dog stadig lade sig gøre at pinge maskinen.
Jeg kan ikke rigtigt finde ud af hvad der går galt, men jeg har fundet en del
fejl i messages logfilen.

Her under er udklip fra min messages logfil, er der nogen her der kan få
 noget fornuftigt ud af dette? Kan det skyldes at der er quota på mine
 brugere?

(Undskyld den _meget_ lange mail, men jeg ved ikke helt hvor meget der skal
til for at man kan få noget fornuftigt ud af logfilen)

Problemet er iøvrigt stort set overstået hvis jeg genstarter computeren en
gang i time, men det er jo ikke helt holdbart.
