Hi Carsten,
I'll take a look to that module to learn how it should be done.
Thanks a lot!.
Carlos.

Hi Carlos,
i hope you are doing fine :-)
You may run into troubles, if your timer process takes too long; so
you might consider using a separate process for "expensive"
operations, maybe you want to look at the nathelper module, which does
the trick.
Kind regards,
Carsten

Hello list,
I have a custom made module which uses a timer to monitor some statuses
in a
period of 1 second. Inside the function
there's a loop that iterates
over a
table that can contain several hundreds of items
and using each of them
to
perform some arithmetical operations.
Under certain conditions, the number of items can grow to a few
thousands in
really exceptional cases and I believe this
situation is causing
Kamailio's
slow timer process to consume more than 90% of
CPU hanging up the other
group of processes.
My questions are:
- What is the best way to perform a repetitive task such as a loop in a
timely basis taking in consideration a precision of at least 5 seconds?
I'm
currently registering a function using
register_timer() call.
- Can a loop that takes more than 1 second to complete be causing this
extremely high CPU consumption?
Below is a copy of the top command when the event occurred:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
22969 root 20 0 2140m 16m 14m R 98.8 0.1 7:22.03 kamailio
Thanks in advance,
