Hello,

at startup all needed components for proper functionality must be available. This was the design from the beginning with many modules. At runtime, Kamailio does the best to recover from fault situations. But it needs to start and have the init state properly build to detect anomalies afterwards.

Changing this behaviour requires to aproach each module one by one. For example, if usrloc is not able to load the location records at startup, then it doesn't know if an incoming register is an update or a new registration, so it has to keep sort of backlog in order to sync with database when it becomes available. Also, restriction such as max_contacts will be invalidated by an improper init state of usrloc module.

Cheers,
Daniel

Hi,

We have verified if MySQL server is offline when Kamailio is starting, Kamailio fails to start correctly.

Is this a bug?

We are running kamailio 3.3.7.
