I posted this note on the general Fedora list a little while ago - I got one response but couldn’t make any more progress debugging F29/30 x86_64 XFCE WS):
"I have been having fairly regular hangs of the whole system - sometimes I have a little warning of a rapidly slowing system and I can systematically exit from all the apps and reboot cleanly - but mostly not and I have to hit the reset button. I used to think it was overloading the (fast) system (with 32GB RAM) with too many Chrome windows and tabs but it happens occasionally when the system is very lightly loaded too. I have new RAM and have checked it with the Pro version of MemTest86 a couple of times so I don’t think it is RAM. I have pretty much replaced all the other bits of hardware now except the MB.
Any suggestions about further debugging would be greatly appreciated!"
I have been interested in Atomic / SB for a while now and have been using Atomic on a big disk backup server for somwtime but now I am thinking that running a WS SB system and containerising all apps - which might help me isolate where the hanging problem is (assuming it is in software . . )? Using containers might cause only a single container to hang instead of the whole machine?
What do people think?
