Package: samba Version: 3.0.24-6etch8 Severity: normal Samba started crashing after I upgraded to the latest version from Debian security and it sends hundreds of emails to me that look like this:
The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 11908 (/usr/sbin/smbd). This means there was a problem with the program, such as a segfault. Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred. The Samba log files may contain additional information about the problem. If the problem persists, you are encouraged to first install the samba-dbg package, which contains the debugging symbols for the Samba binaries. Then submit the provided information as a bug report to Debian. For information about the procedure for submitting bug reports, please see http://www.debian.org/Bugs/Reporting or the reportbug(1) manual page.
