Nyquist (ACX Check)

I am an author who records his books with Audacity. I use a Nyquist plug-in to test each chapter regarding whether ACX technical guidelines were followed. For each chapter, the software indicates “pass” or “fail.” My chapters last from a low of 10 minutes or a high of 35 minutes. Example: Chapter 1 is 20 mins 39 sec.: it passed. Chapter 4 is 30 mins 43 secs: it failed but did not indicate failure. The Nyquist merely stopped the test half-way through. Nyquist plug-in software freezes or is no longer visible. Very frustrating.
In looking at my Audacity Error Log, I read the following message: The maximum number of sample blocks has been reached, so audio computation must be terminated. Probably, your program should not be retaining so many samples in memory. You can get and set a maximum using SND-SET-MAX-AUDIO-MEM. Error: audio memory exhausted.
I have no idea what that means, but I need step-by-step directions to increase memory storage on my office computer. The computer is not connected to any hub; it a stand-alone with plenty of memory.
Can you solve my problem?

There’s a new version of ACX Check for Audacity 2.4.2 and later. You can get it here: https://wiki.audacityteam.org/wiki/Nyquist_Analyze_Plug-ins#ACX_Check
