Hi,
I am facing a problem in QNX with dlt-daemon:
I start dlt-daemon on QNX board and it works fine:

Selection_470

Then I run a scan of port 3490 from a Linux machine:
$ nmap -v -p 3490 -Pn IP_address_of_QNX_board
This leads to a daemon crash:
Selection_471

On Linux machine dlt-daemon doesn't crash:
Selection_472

Thanks in advance.

daemon: Do not exit when accept returns ECONNABORTED (#347)
9fba07b 
Scan of port 3490 from a Linux machine by
'nmap -v -p 3490 -Pn IP_address_of_QNX_board' leads to dlt-daemon crash.

It is necessary to parse the code of the returned error in errno.
If errno = ECONNABORTED it means there was an attempt to scan port 3490
and on this error there is no need to exit the application by error.

Fix for the issue #341
