[sr-dev] Crash bug

[Daniel-Constantin Mierla]

The pid 6979 is the main process here (being the one handling the
signals according to the log), not doing anything at runtime, so it
doesn't crash at runtime. The last error is because of the cleanup it
tried to do, which can happen if another process was doing a cleanup of
the structure but didn't finish because it was killed by main process.

The reason for crash should before the message with "Thank you for
flying ..." -- can you check if you get other relevant log messages
before it?

Cheers,
Daniel
