Hello,
After running out of disk space I found that the file /var/NX/nx/.nx/M-{current session}/session was filling up with the following two events which are each logged several times per second. I have tried decreasing the log level, disabling audio in node.cfg and in the client connection, updating PulseAudio, and upgrading to current version of NX, none of which had any effect. I don’t really care about audio working on this client, just don’t want my disk to fill up.
