randomize_va_space

On a multi Oracle homed (12c and 19c) RHEL 7.9 server, have started to observe infrequent (every 2 months) 'ORA-00445: background process "m001" did not start after 120 seconds' errors from both 12c and 19c instances.  Seeing the same error from two different Oracle releases sort of points to a server kernel issue, specifically kernel.randomize_va_space=2.

MOS Note 1345364.1 implies randomize_va_space was a thing in the past (11g,12c).  However, appears Oracle is still recommending disabling in 19c on Oracle Cloud Infrastructure.

What is your on-prem randomize_va_space?

Thanks,
