----------------------------------------

Hi Walter:

My guess is this is not a deadlock.

[Nov 18 13:49:00] ERROR[25224][C-000029b7] res_timing_timerfd.c: Failed to create timerfd timer: Too many open files
{noformat}

There are two scenarios that could be occurring here:

# You have a rather small number of file descriptors allowed on your system, 1024.
{quote}
open files (-n) 1024
{quote}
Asterisk tends to require a rather substantial number of file descriptors. You should probably increase this limit.
# If increasing the limit of file descriptors does not resolve the problem, then you may be running into a more systemic problem wherein the file descriptors are not getting released by Asterisk. With such a low limit currently in place, however, it is difficult to tell.

I would increase the number of open files allowed and see if this resolves your problem. If not, we can look at how to get information about what is occurring.
