Package: samba Version: 3.0.22-1 Severity: important I know that similar bugs have been reported, but I have not found a way to solve this. I kept getting emails with subject "Segfault in Samba" and have installed samba-dbg as requested. I even upgraded all the packages in my unstable box.
I'll provide the panic email, /var/log/samba/log.smbd, and /etc/samba/smb.conf below. If you need extra information, please let me know. Thanks. ------------------------- This is one of the panic emails I got after installing samba-dbg. To: root Subject: Segfault in Samba From: root Date: Tue, 02 May 2006 21:41:52 -0400 The Samba 'panic action' script, /usr/share/samba/panic-action, was called for pid 16445 (/usr/sbin/smbd). Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred. If the problem persists, you are encouraged to first install the samba-dbg package which contains the debugging symbols for samba binaries. Then submit the provided information as a bug report to Debian.
