Hello,

 

I have experienced 4 random crashes in the last 2 weeks. Today I run memtest86 for a few hours, with no errors. Then I tested the Live Memory Tester for a few minutes, and the server crashed with these updates in the syslog:

 

Does this mean something to someone? 🙂 Why is nvidia mentioned? Thanks!

Not really, but try again, another rapid crash would suggest a hardware problem.

Thanks. I removed the Nvidia driver plugin. Live Memory Tester has now been running fine for 2 hours. Checking the Nvidia driver plugin support forum, for anything similar.

I am now fairly sure it is somehow related to the Nvidia driver/plugin. With the driver uninstalled, the server has not hang/crashed once. If I install it back, the problem usually appears within hours. It crashes even if there is no transcoding going on in the Plex server (which is the only thing I use the GPU for).

 

When it happens, I need to hold the power-button for a few seconds to shut the server down. The flash boot drive got corrupted once, so I had to restore it from the cloud backup.

 

Any suggestions what to try? Older Nvidia driver versions?

 

Thanks.

Suggest asking in the Nvidia plugin support thread

ok, will do.
