C-Gate 2.11.1 on Linux not listening on port 20023

(Apologies ... ignore ... fixed with a reboot)

C-Gate appears to not be listening on port 20023, but is on plenty of others as expected. PICED won't connect to it, but Toolkit will connect fine (which I understand uses 20123, so that makes sense given 20123 is listening).

I'm not seeing anything obvious on this new Linux install of C-Gate that would prevent it, but admittedly this is the first time I've ever done an install of C-Gate on Linux. Ubuntu LTS v16.04.

netstat -tlnp reports the following. Would there be a default setting that restricts C-Gate to only listen on the secure 20123 command port and not 20023?

Ugh. Applying the Microsoft-esque fix of rebooting the C-Gate fixed it instantly. Probably a Java thing relating to copying "libjspLux86_64bit.so" into the JRE lib directory and that not being picked up.
