3 minutes ago@scottwalsh the 64bit version takes about 500m more memory than the 32 bit version…
Thanks for the tip, what’d you recommend as a min swap size? Will just try it off the SD card to start (as don’t have a USD at hand).

@scottwalsh on the low ram machines I set it to 1024m
in the installer script…free -m
will give you defined and used for physical and swap

is already set to 1024

@karsten13 he should examine use and adjust as required…

As @karsten13 noted, defaults to 1024 on a 2W (have done first boot post imaging). Will give it a go at 2048, likely a bit oversized.

Moving to 64bit looks like might have helped. Up for 18 hours since rebuilding so far with my full calendar configuration.
Observation - took about 30 min to boot through displaying the calendar. Load average getting up to 20.0+ during boot, assume swapping a lot via the slow SD card interface. So although looks more stable, much slower performance.

Although moving to 64 bit made it more stable, still found it was going blank after a few days requiring the mm container restarted.
Think the Zero 2W was too under powered for what I was trying to do. So have upgraded to a Pi 4.
-
@scottwalsh and did the problem go away?
-
Installed the pi 4 today.
Was getting up to 4 days on the 02W without it crashing, so will need to give it a week to know for sure.
