[Samba] RE: samba and crash server

Wed Sep 14 12:02:55 GMT 2005

hi,

the smbd daemons are fallting into process status "D" (uninterruptible sleep). The only way to ged rid of these processes is rebooting your system! To analayze why smbd is falling into status "D" you have to check your logs. Another option is building a strace profile of smbd to see what`s going on.

cheers Stefan
