Comment (by andysem):

 As you can see in the strace output, the process does send your message
 (see the last `sendmsg` call with string "<14> Nov  10 15:10:56 WS14
 TEST_"...). The message format is slightly different from the other log,
 but that's fixed in 1.63 (see
 https://github.com/boostorg/log/commit/084f848d1461f16c0a6871694076aa36995d4f80

 and
 https://github.com/boostorg/log/commit/d595b6de33c85ec3bf7c81fc2eb5c4537bdfd786).

 The strace log also indicates that UDP socket-based backend is used even
 when you specify native. This can happen if support for native syslog was
 not compiled in (i.e. `BOOST_LOG_USE_NATIVE_SYSLOG` was not defined when
 Boost was built). I think, this could have changed in 1.62, and needs to
 be fixed. If that's the case, and your syslog daemon is not configured to
 listen for UDP packets, then the messages are lost. You can try rebuilding
 Boost and your code with `BOOST_LOG_USE_NATIVE_SYSLOG` defined and see if
 that helps.
