Performance issues. 22 separate processes no calls

Asterisk Asterisk Support
1

I’m using asterisk 10 and having some performance issues.

Something I have noticed is there appears to be lots of asterisk processes running. 22 separate processes. Is this normal with no calls in progress?

They are threads, not processes.

There is a CLI command which will tell you what they are for.

You may find some are for channel drivers that you have configured in, but with no devices.

Modern versions of linux ps will only show the headline process, unless you use an explicit option to show the ones supporting threads.

Most will be consuming very few resources (most or all of the memory is shared between them).

Yes you’re right
