tl;dr - September patches have done something; not sure if the machine will survive the night but hope is high!
Yesterday I applied 2025-09 server update (2025-09 Cumulative Update for Microsoft server operating system version 24H2 for x64-based Systems (KB5065426)) and left the machine to its own devices with the backup jobs (yeh I forgot to disable them before doing the windows update), which turned out to be 'interesting'.
Having sorted out the mess with a couple of hard reboots (one becasue of the known ReFS issue causig the machine to lock up when it got owards the end of the backup jobs, the other becasue the patch installation got as far as rebooting the machine then just hung with the word "Restarting..." on the console) I kept an eye on memory use.
What happened was that the indicated memory use climbed steadily, then dropped back a bit and then instantly climbed a bit, then gradually increased until it was higher than the point at which it dopped back, rinse and repeat to a max of about 80Gb. It stayed up high for quite a while then dropped suddenly to about 20Gb and there remained for a while.
Whilst typing this memory use appears to be slowly rising again - about 100Mb increase every 8-16 seconds or so. It reached about 28.4Gb and just dropped back to 24.3Gb again - no, wait, its dropped again to 16.3Gb and is slowly climbing again; this seems to be cyclical - definitely repeated the 16Gb to 28.4Gbish slow climb then drop back to 24Gb then 16Gb a couple of times.
Pure speculation - something has changed with yesterday's patch that makes the system much more likely to free memory for whatever reason.
With that optimism in my heart I am going to let the backups run tonight and hope to be able to say "it's all still working" in the morning![:lol:]( "Laughing")
