[Resolved] 7.95.1 - Instability

Hi,

Got another bug for you - I'm sure you'll all be pleased to know. Please find logs attached.

During video playback something is going wrong. Occasionally, the PI suddenly becomes unstable and video playback begins to stutter. After a couple of seconds, playback then halts altogether. In this example, I tried to change channel and I was able to get the guide on screen. However the channel did not load and only presented a dialog busy spinner. I then tried to stop at which point the dialog busy stoped turning. Then PI crashed over completely, Kodi exits and the screen goes black. The only option is to cycle the power.

I know this is happening often but this is the first time I've been able to get the log files for you to see. I can't force this behaviour. Would I be right in thinking you might have a patch for this already? I remember reading a commit within GIT from the past couple of days that sets a minimum CDVDClock parameter or is this a different issue?

Please take a good look through the logs, you will note that at the moment, the PI is VERY unstable and is needing to be restarted after every few or so hours. Each crash feels different. If your able to help with why this is happening I would be grateful.

Is it possible there is a problem with your MySQL server or network?
Can you try disabling MySQL and play some files and see if kodi is stable or not?

I did see this but kind of disregarded it because all the other PI's in the house were OK at the time. I've got 4 Pi's running Libreelec in the house and none of the others stopped responding at the same time. I have DVBLogic & SQL on a dedicated server and all clients are cabled to it though the same gigabit Ethernet hub so I would have thought that if there was a network issue, even if it was a minor glitch, they all would have fallen over together. I also think this error was produced after Kodi became visually unresponsive and might be a result of the crash as it's the very last entry before I cycled the power.

Because they are in use more or less 24/7, we even use the PI's to listen to radio over night, I see a lot of crashes. I'm sure they crash over even more often than I know about because I have to try and find issues by keeping an eye on logs and up times - everyone else in the house has got bored of telling me when they break. I just happened to see this unusual crash as it happened so I thought it best to mention it here.

I've found another example. This crash looked similar but is on a channel change this time. I've omitted nothing from the logs and it seems the PI became unresponsive, without error for a few mins before the power was pulled. Any ideas?
