Workload:
Mixture of compiles and later on accelerator device I/O through
multiple docker containers. It usually takes days before the problem
is triggered.
I'm afraid I don't have the iostat/vmstat during the time of the
problem recorded
If there's key information missing that I can supply let me know and
I'll try and get it to you.
