Hi everyone, I’m looking for some help troubleshooting periodic system hangs. My server becomes completely unresponsive (web UI and SSH) after a day or two of uptime. The lockup is so severe that I am forced to do a manual hard power reset, which leads to an unclean shutdown detection on the next boot.

Hardware/OS:

• Unraid Version: 7.2.0

• Motherboard: MSI MAG B550 TOMAHAWK

• CPU: AMD Ryzen 9 3900XT

• RAM: 32GB (2/4 slots populated)

• Network: Using Realtek r8125 and r8168 drivers. I recently attempted updating these Realtek drivers to see if it would resolve the issue, but the hangs persist.

The server runs fine for a while, but then hangs completely. Looking at my syslog mirror, I’m seeing a massive amount of shfs: share cache full errors right before I have to pull the plug. My cache drive is a 500GB Samsung 980 PRO.

Attached are the syslog recovered after the hang and the diagnostics.

Any help is appreciated here.

Thanks.

Thanks @JorgeB for replying.

I have updated the Bios setting according to the comment you referred.

I will wait for a day or two and see if the issue is resolved.

Hi @JorgeB, the bios setting worked. It's been more than 10 days and server is running smooth.

Thanks a lot for the help!!!
