<tt>Shortly, what Eric wants to say is that your timer interval to
ping is too short to actually manage to ping all your contacts.
Like you want to ping every 30 seconds, but to ping them all (one
time) takes 40 seconds.<br>

Hey again Rodrigo,<br>
<br>
I had further discussions with Bogdan which I will summarize here
in an attempt to clarify.<br>
<br>
Because the new 2.x system is implemented as a reactor, the
implementation of timer based callbacks has changed. There is a
single timer process who's only job is to keep track of jobs that
are to be scheduled, when it decides a job/callback needs to
happen because of the current time, it writes to a shared pipe
which is read by ALL other processes of the reactor. Any reactor
process that is free, will take this callback off the pipe and run
it. In this way, there is no way to actually block the timer
process. <br>
<br>
However, what can happen, and what I believe you are seeing here
is that the timer process has not finished going through the list
of timer handlers and it should have started processing the list
again already - so the timer list scan is overlapping.<br>
<br>
I'm not 100% sure how this can happen, perhaps you have a very
long timer list and it is causing the timer process to fail to
complete before its next scheduled iteration - either than or it
is not able to write to the shared pipe for some reason. <br>
<br>
I would bring the question to either IRC, or to the devel list
with as much detail as possible.<br>
<br>

<div>I was just speaking with bogdan, apparently i am
wrong. he said:<br>
<br>
"no, there is no way to do that, as right now any process
(SIP worker) can execute (if free) the timer jobs, and the
timer_partitions in TM has nothing to do with that change
(in how timer jobs are executed)"<br>
<br>
So ... i guess you need to prevent any type of blocking
operations ...<br>

<div>I believe this has been refactored under 2.X as
a result ofthe async work. I think the new

<div>Many things share the same timer,
dialog expiration cleanup, userlocation
cleanup, nathelper pings etc. If one of
the processes that is triggered by a timer
route blocks for some period of time - aka
a hung db query, it will cause the timer
to "drift" and you will get logs
indicating that a process that should have
takeng X amount of time actually took Y
amount of time - this is due to the
blocking operation.<br>
<br>
I would suggest that you use dedicated
timer processes for as many things as you
can - dialog, tm etc. see the module docs
for how to do this.<br>
