In August we had five crashes in the CheckRequest database. They all occurred when a user created a new request, and apparently after the code had reached AddRecord statement. This has been a problem for a long time. BUT, there have been no crashes in that DB since August 23, 2021. (More than 150 requests added without a crash.)
I would tentatively say that whatever caused those has been resolved.
Hoorah!
(I am not saying other DBs are crashing; but I just happened to review this one today.)
