Hi,
I use 'rtimer' and 'mqueue' to asynchronously defer certain heavy DB
tasks on which call processing does not depend.
I was hoping to get a clarification on the exact behaviour of 'rtimer'
when tasks don't complete as fast as they should.
Let's say that I set the rtimer route interval to half a second (500
ms), as afforded by new Kamailio 3.3.0 capabilities. What happens if
the tasks I am running inside the rtimer route don't complete in that
interval? Is that rtimer thread forceably terminated, or is it allowed
to run as long as necessary to complete the task? Is there an absolute
timeout? If the latter, I assume that another, parallel rtimer route
will be started in the background after 500 ms. I am given to
understand that there is a thread pool. How big is it? Can I configure
its size anywhere? Is there a practical limit?
Finally, is there 100% assurance that 'mqueue' is safe to consume for
multiple rtimer processes, possibly ones tripping over each other due to
unpredictable delays? Or is it designed only to provide blocking mutex
for data passed from a SIP worker thread to a different kind of thread?
Thanks!
