A new Flyspray task has been opened. Details are below.
User who did this - Øyvind Kolbu (kolbu)
Attached to Project - sip-router
Summary - tls module crash on initialization when used together with the dialog module
Task Type - Bug Report
Category - dialog
Status - Assigned
Assigned To - Timo Reimann
Operating System - Linux
Severity - Medium
Priority - Normal
Reported Version - Development
Due in Version - Undecided
Due Date - Undecided
Details - I've tried to enable the tls module, but if the dialog module is loaded the
tls module
crash. If I disable the dialog module tls loads fine.
Note that if «enable_tls» is «no» Kamailio doesn't crash.
Tested both on latest 3.2 and master branch.
Built only with db_postgres and tls modules. Running on 32-bit RHEL 5.
