After a burst of activity, the process (eg. logger_proxy) could stay with a large heap for a long time. While here, produce a bit less garbage in the first place.

After a burst of activity, the process (eg. logger_proxy) could stay with a large heap for a long time.
We had a situation (using OTP 28.4.2) where a large process crashed and the
logger_proxyspiked to over 10GB, then went down to a few GB but stayed there, because there was no further logging activity, and therefore no GC. Hibernating when idle seems like an easy way to avoid such situations.While here, avoid some temporary map creations to create a bit less garbage.
