My server is crashing/becoming unresponsive at almost regular 7 day intervals since 6.2.1 (although i don't believe it is 6.2.1 directly causing this), it always seems to happen somewhere between twenty past midnight and 6am and needs a hard reboot.

 

I would like some advice on how to track down the cause of this, as diagnostics and logs do not keep a record from before the hard reboot.

 

Prior to 6.2.0, my motherboard died, would get stuck at the bios screen (Gigabyte + i2500) and i replaced it with an Asus A88XM Plus and and AMD A8-7600.

 

All plugins, VMs, RAM (32gb) have remained the same as previously installed. The main issue i have noted with the AMD is the passthrough of my graphics card which shows the below in the logs

and the passthrough of the USB3 card which is in the same IOMMU group as my ethernet controller which stops the VM from starting, using  ACS override causes major instability issues so that is currently not assigned but does make me think the current weekly lockup is due to my graphic card assignment to the VM. The graphic card is set as the default device in the bios.

 

diagnostics are attached but not too informative, my current plan is to leave my VM off for the next week or two to see if that is the cause unless someone can throws some ideas in?

 

Thanks

Mine has become far more stable under 6.3 RC4 onwards. I narrowed it down to my windows VM which RC4 solved and using a USB3 cache drive and the cable being dislodged slightly causing dockers to crash and lock up the system. But as RobJ suggested use the troubleshooting mode of FCP

 

Glad you were able to solve it!

 

And thank you for your patience with us.  We're all volunteers, with lives of our own and not always able to respond quickly.
