Open a bug at bugzilla.samba.org and add the line: panic action = "/bin/sleep 99999" to the [global] section of your smb.conf. Once the crash re-occurs, attach to the parent process of the sleep using gdb, and then type "bt" to get a full backtrace with symbols. Attach this to the bug report please. Thanks !

BUT I read the "3.4 Panic in Debian" thread and Ubuntu 8.04 is shipped with libkrb53 - 1.6.dfsg.3~beta1-2ubuntu1.3 May that hit my problem too? -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba |
