Compact database became problematic again in Windows 11 while engine windows are open

[daSilva65]

Two or three days ago had a crash during the compact database process. Today had another. After closing both engine windows (Engine: Stockfish 17 and Analysis: Stockfish 17) compact database process was right and fast.

P.S. Using version 5.1.3.35

@daSilva65 : thank you for letting me know. I don't think I have a good fix for this other than prohibiting engine windows from being open if the "compact" utility is selected. However when I implemented that rule before it proved to be unpopular with other users (and no one else seemed to be having the crash issue).

Seams like when the windows are open the engines have RAM attributed in the activities panel even doing nothing. That is managed by the operative system and not by scidCommunity. Well, if some more people report the issue, the rule can be implemented again. Anyway it could be written into the help file, saying an user reported the issue and its solution.

That's a good idea to include it in the help file. There is no question that RAM issues can cause scidCommunity. I've gotten that when I've opened too many engines that want to use more ram than I have available.

Engines set with huge hash memory attributed, most likely.
