Hello, this is really strange, the structure could never be filled with zeroes under normal circumstancies. At least domain and aor must be set to non-zero value. After the structure is created these fields are automatically set. And they must be non-zero otherwise the structure would never be created. So either gdb doesn't show correct values or the memory has been corrupted somehow.

Is anything suspicous in your log files ? regards, Jan. On 02-04 22:54, Maxim Sobolev wrote:

We have been running ser for very long time without any problems (I think that locking problem would show up on iptel.org - it's registrar is very active). Could you please tar the sources along with the core dump (and log files if possible) and send it to me ? I currently have no clue why such a mysterious crash happended (it can be even HW problem) but I'd like to review it later.

On 03-04 01:33, Maxim Sobolev wrote: Are you using a CVS snapshot ? I though that you are using 0.8.10 (from the info you sent me). auth_radius module is not available for 0.8.10 (it was called radius_auth). The situation you describe is not possible. radius authentication is done in a different module and save() is executed after the authentication completes successfully. So it doesn't matter how long the radius query takes. And both save() function and the timer are protected by a mutex so they cannot modify contect of user location database at the same time. What version of ser are you using ?
