yes… this is to much. For lot of users with less that 32Gig RAM it was helpfull to set a overall-memory by around 32 Gig… Therefore e.g. the recommentation with 16Gig RAM: virt. mem 4min/20max.
With already 64Gig RAM, you can simple set 1Gig Min / 4 Gig Max and you will never see that more as 1Gig is used 
I read in meanwhile lot’s of threads and it comes more often on top what we already mentioned and what you also find out:
- the network related settings makes trouble. Some users have more issues with that, some users zero issues.
All the older Workarounds are:
- set Generic Models = ON ( both )
– seems there are issues if mods are installed - set Text2Speach=Windows Offline
– with Azure-Setting seems ctd happens again in rare cases - set AI / live traffic Off ( network related settings )
– next to outdated mods, this was often reported as one of the main reason
