SUMMARY When an INDI driver crashes and gets restarted by the indiserver, EKOS does not handle this properly. In these cases, EKOS simply hangs and KStars needs to be killed. STEPS TO REPRODUCE 1. Start KStars and connect to an INDI server 2. kill the process of one of the INDI drivers OBSERVED RESULT On the INDI side, the INDI server restarts the driver. EKOS simply hangs. In the debugger, the problem occurs in INDI::BaseClient::disconnectServer() at line 291: listen_thread->join(); It seems like listen_thread is waiting for something. At least, it does not terminate as expected. EXPECTED RESULT EKOS should handle the driver restart as offered by the INDI server. SOFTWARE/OS VERSIONS Linux: Debian 10, Raspbian 9 and Raspbian 10 show the same behavior.
