[Samba] Winbind dumps core after upgrade to 3.2.6

[Michael Adam]

Hi François,

yes, please file a bug report with this issue,
providing configuration detais and log files.


If possible, a more meaningful backtrace would be helpful:

* Be sure to compile with debugging symbols (cflag "-g").
* add 'panic action = "/bin/sleep 90000"' to your smb.conf
* restart winbindd
* reproduce the panic. "ps axf" shows the sleep process as
  a child process of the panicing process
* attach gdb to the process with "gdb --pid" and do a "bt"

Cheers - Michael
