Server Hang – Kernel Upgrades 1/12/2023

     The server that provides home directories and also shared web services as well as two virtual private servers hung with the CPU stall bug even though we’re about 12 incarnations down the road from where it first appeared.  We know this seems to be a use after free error in the kernel but kexec is not finding it.  The kernel developers have asked me to compile in KASAN which is another memory allocation debugger, the system is now running that kernel and hopefully if it hangs again it will provide some debugging information.

     Between yesterday when I compiled the kernel and today, 6.1.5 has come out, so I am going to try to get kernels ready for another upgrade tomorrow evening and if I make it we will be doing a kernel upgrade at 11pm.  This affects all eskimo north services.
