I'm dropping this from major to minor as it isn't clear what the issue is really here. I see the WARNING and NOTICE, but there isn't any additional information about how this was produced, what happens when the notice and warning messages come up, or any backtrace when this happens, or other useful information.

Please disregard this issue.

The problem was with generating more calls, but it was solved by increasing max file descriptors:

ulimit -n 32768

Perhaps it would be a good to mention this in warning message:

WARNING[14063]: channel.c:830 __ast_channel_alloc_ap: Channel allocation failed: Can't create alert pipe! Try increasing max file descriptors with `ulimit -n`
