[OpenSIPS-Users] core dump in dialog

Hi Jennifer,
The crash seems to happen when checking the sharing tag used for dialog
replication. Maybe you could install the debug symbols (it is a separate
package) to get more information in the backtrace.
As a note, if you want to only do sharing profiles, you do not have to
do dialog sharing also - the two (dialog sharing and profile sharing)
are completely independent.
Best regards,
