Actually, I had to stop using the software because when I hit 1000 calls, Asterisk blew up, and it took down the container as well, since I tried to type any command and I got “cannot allocate memory”. Posted a question to the Asterisk devel group and got this:

This sound like you have run out of file descriptors. Asterisk needs file descriptors for each port it opens (so having 2 SIP channels bridged, both with RTCP and video you need at least 8 file descriptors per call)

I need to make sure that all files and resources are available for Asterisk. How do I do that in a container?

A little bit more information would be useful, i.e. how can we reproduce the bug (command line options?)

I always get this error when I run vztop:
205 processes: 204 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 0.1% user 0.1% system 0.0% nice 0.0% iowait 98.0% idle
CPU1 states: 0.0% user 0.0% system 0.0% nice 0.0% iowait 100.0% idle
Floating point exception
My machine is available for inspection. I need vztop, since I decided to put all my business in this technology. My box is up2date.
Yours
Federico
