I’ve been using Ubuntu 18.04 on a Raspberry Pi3 (ARMv7) with NoMachine and it was working fine connecting to it from a Windows client. Now I’ve upgraded to Ubuntu 20.04 and I cannot connect anymore and it’s telling me that no available sessions on this server. I have noticed the a huge number of entries are created under the /usr/NX/var/log/node directory, 24960 entries in about 48 hours and the session files contain this:
NXAGENT – Version 6.10.12
Copyright (C) 2001, 2019 NoMachine.
See http://www.nomachine.com/ for more information.

Attached is the archive containing the log files. I have deleted most of the entries from /usr/NX/var/log/node.
