I found this bug report which indicates that 4.1.10 works:

  <https://issues.asterisk.org/jira/browse/ASTERISK-25251>

But in your original report, you said that 4.1.13 is broken.

This backtrace:

  <https://issues.asterisk.org/jira/secure/attachment/52702/bt.txt>

shows a lot of waiting on quite different netlink sockets.  So if this
is due to a race in Asterisk, it must have happened several times in a row.

Thanks,
Florian
