Track stops playing with CDSP Plugin ERROR: XRUN OCCURRED!

[Sehnsucht]

I listened to approx one hour of music when suddenly it stopped 5-10 mins into the fourth track, where each track was around 20 minutes long.

 /var/log/mpd/log contains over 2000 of these:

CDSP Plugin ERROR: XRUN OCCURRED!

I checked the flac file in Audacity and it looks fine.  Played it again and it's fine.  I've recently performed a fresh install of moOde 8.1.1 and I play purely local flac files from a USB attached hard drive. I use CamillaDSP with a fairly simple EQ (3 filters plus gain, on two channels).  I've never had this problem before using moOode/CamillaDSP on recent moOde v7/v8 and I've listened continously for much longer than an hour on this and previous installs.

I'm using a Pi 4 with 2gb ram, into an external DAC over USB.
