[Bug]: Failed to auto-import playlist /data/mstream_data/_MusicPlaylists/XXXX.m3u

[litebito]

What happened?

When I noticed that my playlists were not updating with newly added tracks, I checked the logs, and (probably already for some time) I see messages Failed to auto-import playlist for every playlist now.

I upgraded to the latest Airsonic version, and it is still the same.

I had this issue in the past, then it disappeared for a while, then it came back ....

Steps to reproduce

1. Export the playlists from my main mediacenter (Jriver) to disk on my NAS (Qnap)
2. Sync the playlists from my NAS to a dedicated directory on my streaming server (Centos 7 server with Airsonic)
3. See in the airsonic log the "failed to auto-import" message.
4. Remove some playlists from Airsonic, remove them from that directory in Centos
5. Resync from NAS to the Centos server
6. Still the same error

JAVA_JAR=/var/airsonic/airsonic.war

# Set any java opts separated by spaces
JAVA_OPTS=-Xmx2048m -Xms2048m

# Set a different location for airsonic home.

# Change the path that is listened on

# Add any java args. These are different than JAVA_OPTS in that
# they are passed directly to the program. The default is empty:

# Note that there are several settings for spring boot, not explicitly listed

# For example to set debug across the board:
#JAVA_ARGS=--debug

# Or to change the ip address that is listened on:
#JAVA_ARGS=--server.address=127.0.0.1

@litebito May I ask for the m3u file that is causing the issue? It is okay to delete any sensitive information.

[litebito]

This is an example. Fotoshoot.m3u.txt

It's strange behavior... after a few reboots of the server, they start to import again... then after a while, the error comes back
