When there's heavy activity on a larger file server, these messages are possible. It should not happen in quiet periods. I just checked now which is a quiet period and indeed, the messages do not show. One less thing to worry about :-) Regards, Dan -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

[Samba] Issue with Samba version 3.0.25b on Debian
Hi, I have an issue with Samba version 3.0.25b on Debian. I am receiving a number of mails from my server with the following: The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 18483 (). This means there was a problem with the program, such as a segfault. However, the executable could not be found for process 18483. It may have died unexpectedly, or you may not have permission to debug the process. Also, when running 'smbstatus' I get the following at the bottom of the output: -- tdb(/var/run/samba/locking.tdb): tdb_rec_read bad magic 0xd9fee666 at offset=678200 locked file list truncated -- I'm not sure what's happening here as it only seems to do this once in a while. If I restart samaba it will be OK for a week or so but then I will have users report that open files are locking up etc, then I start receiving the panic e-mails and have to restart the process again. I am away until next Monday now but will reply on return, in the meantime I'd be most grateful if anyone can help me out with this issue!
