Bug#501773: Additional details
Christian Perrier написав(ла): Quoting Steve Langasek ([EMAIL PROTECTED]): There was plenty of information in the original bug report. Hmmm, correct, I was missing the original BR. The problem happened with 3.0.24 from Etch. I suspect this might be on a production machine where trying to reproduce it with the version of samba in lenny is far from being easy. Am I wrong, Yuriy? I'm OK to keep crash bug reports opened for versions of samba in Etch but I doubt that we will ever do anything with them...:-) Hi Christian, Yes, it is production machine, but I may try lenny package. It is not very critical file server and it's well backed up daily :). I'm getting these error message few times a day, so I think I'll see if it works very quickly. Can you suggest me or point me to some guide how to do it safely, so I can then return to etch package easily? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Bug#501773: Additional details
Today I got such mail from root, but as I see there are no much details :( The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 4756 (/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.
