linux guest processes terminated after win10 host sleep

Windows 10 1904 host Ubuntu 20.04-LTS guest (created with 6.1.10 IIRC) virtualbox-6.1.14 with 6.1.14 extension pack

situation occurs when host goes into sleep on its own (my power settings are set never to hibernate when on line power)

result:

• running apps and windows in guest are all exited
• docker containers are exited
• system uptime seems to be correct

in attached log, the situation likely occurred starting at "07:39:12.135290" as this delta from the log opened time corresponds to the time docker reports my container exited
