Many thanks Andrew.   I would if I could!    I have no idea at all how to do that.   I see that the gdb_backtrace script is included for self-compiled versions, but I can't see it on the system with Louis' compiled version.   I assume I would need to install gdb and use the script (copied from the sources of 4-15.2)?   How is the script invoked?      Problem is I don't know how to trigger the Panic action - it happened this morning when I was out, but there may well have been some backups running accessing the shares on the server.

If you can give me some guidance I'll try to do what I can to capture the event.
