Hi,
We're running samba-3.0.0 in out production environment for half a day
now and have caught about 300 panic actions. Who wants them for
analysis? Samba-3.0.0 is running on RedHat Advanced Server 2.1 on our
compaq proliant DL380G3 server with 4Gb mem and 2 cpu's.
Here is one sample:
The Samba 'panic action' script, /usr/local/samba/lbin/panic-action,
was called for pid 27845 (/mnt/clusterAdg/applications/samba-3.0.0/sbin/smbd).
Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occured. You are
encouraged to submit this information as a bug report to Samba.
