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

             Summary: Asterisk crash with netlink error 
                 Key: ASTERISK-27205
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27205
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_rtp_asterisk
    Affects Versions: 13.15.0
         Environment: Linux Ubuntu kernel 4.4.0-83 with glibc 2.23 and asterisk using internal PJSIP 
            Reporter: Abhay Gupta


There is segmentation fault that causes crash and bt is attached , it seems that Nelink error is the cause and can be seen from this changelog of glibc 

https://abi-laboratory.pro/tracker/changelog/glibc/2.23/log.html

getaddrinfo now detects certain invalid responses on an internal netlink
  socket.  If such responses are received, an affected process will
  terminate with an error message of "Unexpected error <number> on netlink
  descriptor <number>" or "Unexpected netlink response of size <number> on
  descriptor <number>".  The most likely cause for these errors is a
  multi-threaded application which erroneously closes and reuses the netlink
  file descriptor while it is used by getaddrinfo.

this signal is not captured causing it to crash .
