Hello,<br>
<br>
I am running kamailio 3.1.3 and I am making some tests with the
exec
module. I am running a "dummy" script and it worked like a charm.
<br>
Now, I am testing what happens when the script takes "too much
time" to
return a result. According to exec module documentation the<i>
time_to_kill </i>parameter should take care of it.<br>
<blockquote><b>time_to_kill</b> (INTEGER)<br>
<i>Specifies the longest time a program is allowed to execute.
If the
time is exceeded, the program is killed. </i><br>
</blockquote>
BTW ... I am assuming <i>time </i>is in milliseconds. I think
the
documentation should refer the time units.<br>
</blockquote>
thinking of the time when the module was implemented, the unit is
second. Have you tried with a lower value, short enough to be
visible in seconds time?<br>
<br>
Cheers,<br>
Daniel<br>

Apparently kamailio ignores this parameter (or it doesn't work as
I am
expecting). No matter which value I assign to <i>time_to_kill</i>,
kamailio doesn't kill the script and waits for the script to
finish. In
the meanwhile some SIP timers are triggered ... resulting into a
failed
call.<br>
<br>
The test I am doing is quite simple. For incoming INVITEs, use a
external script to check the status of a specific test user, if it
returns the keyword "busy" sends it to voicemail otherwise route
the
INVITE to the local user. The test script returns a result after
about
8 seconds.<br>
<br>
Shouldn't the <i>time_to_kill</i> be triggered and stop the
script? <br>
<br>
Here goes some relevant parts of my configuration. In attachment I
am
sending the kamailio log with a debug value of 4. <br>
<br>

<blockquote><i># ----- exec params -----</i><br>
<i>modparam("exec", "time_to_kill", 10)</i><br>
<i># --- exec params end -----</i><br>
