Hello,
I'm quite unsure about openser's hangling of message processing. So can
anybody answere following 2 questions please ?
1. When multiple messages come in, lets say 3 INVITEs. Will openser fork
one child for each message, run the route script and terminate the child
after that? Or will openser throw all 3 INVITEs at the same time into
the route script?
no - openser has a fix number of worker processes (handling SIP traffic)
- the received packages are read randomly by an idle worker and
processed. There are no dynamic processes.
2. If the 3 INVITEs share the same route script, are
they handled
sequentially? What happens to the AVPs and $var variables? Are they
gonna mixed?
Requests cannot share the script - each processes handles only one
request at a time. Of course, multiple requests can be processed in the
same time, but by multiple processes and with no interferences. The AVPs
are per request/transaction. $var are persistent across a process.
regards,
bogdan

Helmut
