Hi guys,

 

I had this problem before and I thought it was because the controller card overheats.. I have tried resit the controller card, changing out new cables etc, and it was stable for about 200 days until today... I was transferring some larger files from disk to disk, then it started freezing again. I then force reboot the server and now it keeps on freezing every time I run a parity check. Here is the syslog: 
My controller card is LSI Logic SAS 9207-8i with a 40mm fan blowing directly onto the heatsink

Please help, because I have some very important files and I've been working on... after 5 force restarts, I am literally afraid to start up the server again... Many thanks!

Try a different PCIe slot if available, if the same try another HBA if you can.
