[SOLVED] RPi3A+ Network instability.

Interesting. If the CPU gets pegged it would explain the unresponsiveness of the system.

The components involved in a Library update are:

MPD
/var/www/util/list-songfiles.sh
/var/www/util/thumb-gen.php

The list-songfiles.sh command is run by thumb-get.php and it pipes it to sort. Since sorting can be resource intensive I'd try running the command stand alone and monitor it with htop in a second SSH term.

Code:

# Default is from the Prefs setting COVER ART > Audio formats

sudo /var/www/util/list-songfiles.sh Default | sort

Well, it certainly isn't that command that hangs.  The whole thing run in about 5 seconds.  The initial "find" part gets permission denied errors on the eaDir folders, then the "file" part runs so fast that the console becomes a blur as the output whirls past.
Snippet here:

Code:

find: '/mnt/NAS/Claudia/Will Young/Friday\'s Child/@eaDir/06 Dance The Night Away.m4a': Permission denied
find: '/mnt/NAS/Claudia/Will Young/Friday\'s Child/@eaDir/09 Going My Way.m4a': Permission denied
find: '/mnt/NAS/Claudia/Will Young/Friday\'s Child/@eaDir/04 Leave Right Now.m4a': Permission denied
