[ace-users] Issue after re-install of ACE 6.1.0 on Fedora 23

[Johnny Willemsen]

Hi,

The 6.1.0 is getting pretty old, would recommend you to upgrade to ACE
6.3.4.

You are spawning a worker thread, do you have a wait on the thread
manager at the end of your main to wait on your worker thread to have
finished before existing main?

Best regards,
