As several others have reported over the past couple of days, I'm also getting a 'Call Traces found on your server' error reported by fix.common.problems. It seems unusual that several have reported identical errors since upgrading to unRAID 6.3.1. Does anyone have any ideas? (This is a server that been running unRAID for several years without issue.) I've attached diagnostics.

 

Thanks in advance!

It's a new feature of Fix Common Problems that just happened to coincide with unRAID 6.3.

 

Here's your problem:

Page allocation stalls for nearly 20 seconds. Since it's memory related I'd run Memtest for 48 hours, look for a newer BIOS and try a new kernel as soon as unRAID 6.3.2 is available.
