Official moOde 7.0.1 support thread

[Alaini93]

Hi,
Reposting #36

I have a problem, when playing songs, everything is fine, when the system is paused or stopped (no more song playing), after 20 minutes the system get stuck, cannot login ssh, or access UI anymore from any devices.
I can see that chromium memory jumped to 75% here(usually 15%) and kswapd0 7%CPU.

What could be the problem?
Do you need to see any log? (hard to get a log when everything is stuck)
Moode acted like that since I first installed 7. At first I thought it was because of a modification, spectrum, boot up splash screen, shutoff button, but with no mod, it's still getting stuck.
I have Local display enable for 3.5" screen
Alain

After more than an hour Moode got unstuck, and the local display is not showing the UI anymore, just a white page with "Aw, snap! Error..."

By the look of it (threads http://moodeaudio.org/forum/showthread.php?tid=3308 and  http://moodeaudio.org/forum/showthread.p...55&page=35) you are modding the standard MoOde build. This is NOT a criticism.
Is it possible that a certain config line may cause the trouble? Could you run a new unmodded build and test for a while?... and then introduce the addons one by one...?
Does the issue (<< the system get stuck, cannot login ssh, or access UI anymore from any devices  >>) happen when you pause any source, RADIO or NAS or external USB storage?

Hi Mike,

in my post I said I tested it without any modification.
NAS is my source, music is store on another computer.
But I remember having Moode getting stuck without playing anything after power on, and I realized that it was frozen after an hour, trying to play something.

I'm trying to get all my mods set up like 6.7.1, and I have multiple sdcards that I switch to try things.
Anyway, thanks for answering something, because it's radio silence on that one.

After fresh install of 7.0.1, I noticed, there's this error in the moode.log. It doesn't go away even after reboot.

Code:

watchdog: Error: PHP session permissions (reapplied)
watchdog: Error: PHP session permissions (reapplied)
watchdog: Error: PHP session permissions (reapplied)
watchdog: Error: PHP session permissions (reapplied)
watchdog: Error: PHP session permissions (reapplied)

Quick troubleshooting revealed, that when the watchdog.sh is started during boot, the SESSION_FILE variable is malformed (sets to /var/local/php/sess_), because the db is not yet ready to return the sessionid. As a result, the ls -l fails to locate the file, PERMS remains empty, and the subsequent test evaluates to True:

https://github.com/moode-player/moode/bl...dog.sh#L49

As a remedy, I added a small check to wait until the sessionid is returned, and only then continue the execution of the rest lines. Tested locally, works fine, no more false errors in log, since PERMS is now correctly set to '-rw-rw-rw-,www-data,www-data' value.

To contribute the project, I raised a PR. Feel free to edit it, if you have more elegant solution:

I'll see if I can repro.

[Tim Curtis]

The session id is a static value in cfg_system and thus would always be returned but what I think is happening is the sql query is failing because the database is busy processing an update. It's due to an order of execution issue in worker.php. See the code snippet below.

Code:

// Start watchdog monitor
sysCmd('/var/www/command/watchdog.sh > /dev/null 2>&1 &');
workerLog('worker: Watchdog started');

//
workerLog('worker: Ready');
$result = sdbquery("UPDATE cfg_system SET value='1' WHERE param='wrkready'", $dbh);
//

//
// BEGIN WORKER JOB LOOP
//

The fix would be to start watchdog after the update query for "worker: ready".

If you cold revert your change to watchdog and test this fix I'd be interested in knowing the results.

Hi,

 Here what I get after power it on this morning, didn't play any song, just left it on with "top" running to monitor.
Of course now it's stuck, cannot access UI from anywhere, and SSH is stuck too.

If it's something that nobody wants to look at, you need to tell me, I will stay with 6.7.1

Yes, it is the sql query that fails. I was not very precise in my wording initially.

OK, I'll test this in coming days.

See you in 2021

If you can provide a list of steps that can be used to reproduce your issue then it might be possible to troubleshoot.

ok,
Flash moode-r701-iso.zip with BalenaEtcher
Power on,

System:
expand file system, restart
set time zone
set wifi BT off, restart
local display On Mouse Off, restart
Set screen blank 1 min, Wake dispaly ON, brightness 
Metadatafile ON, restart
LCD update engine ON

Network:
Set Static IP, restart

Audio:
Set Device, restart
Set Spotify.

Library:
Set NAS source.
Update library.

Preference:
Coverview, automatic display 1 min

Go to config.txt set blanking=0
restart


Here are all the steps.

BTW, is there a way to save that setting, so we don't have to spend 10 mins resetting everything every time we reflash?
