Zero 'information' on any of the SM logs, when it first crashed....
To be clear. I rebooted 3 times in 5 hours. Stopped SM 6 or 7 times in same period.
Out of all of those instances, there was no major data written / reported in SM.
I did look in the Window logs the first time it crashed... nothing was there either.
But... Duh... thanks for prompting me to look at the Windows log again.. { I didn't think to look there again after the first reboot/crash because the box is relative new (less than 2yrs old}.
So on the second reboot (11.15 am CST), in the Windows Log:
In the second 'reboot', I saw "The IO operation at logical block address ' =Event 153
Now, having been down this road before... one might **think** that this is a hardware issue......
not necessarily - this has to do with Windows vs. X = Where X can be Windows or any application running under it. Could be related to BIOS / new updates from Windows or any application... can be caused by any number of things.
All of that means that Windows isn't writing out from a buffer.. either because it can't or because the application ( X ) has delayed.

What that means in this instance.. I don't know. The errors existed for about 2.5 minutes during one of the memory crawl upwards, but not in all three times that I rebooted or in all cases where I just stopped / restarted the SM service.

Outside of that.. none of the other restarts or reboots really yielded anything.
One other thing of note: During these memory crawls... SM reports / dashboard would should show that it was using 12% memory (not sure what really represents) - and reports would show 450 MB or memory, Meanwhile Task Manager would show 1,314 MB being used,

Event 153 - Is Disk related.... so I will monitor for next couple of days and run a : ‘sfc /scannow’.
when we rotate the box out

Have to conclude... that although SM may have had a part in the server crashing.. due to eating memory, the root cause probably lies else where......
Although it would still be good to know - if there is memory "recipe" or calculation somewhere.
