Description Mark Brown 2017-09-21 01:09:14 UTC 
In Calc I copy a very large amount of data to the clipboard.
When I close the program, it closes but the process soffice.bin continues to run and run for more than 5 minutes during which time I can not relaunch the program.
If I run C:\Windows\System32\cmd.exe /c "echo off | clip" , this clears the clipboard and I can immediately relaunch the program. You might consider the option "You have a large amount on the clipboard. Would you like to clear it?"

The summary is a bit misleading, but I agree with the suggestion in comment 1. 
LibreOffice will keep running in the background after closing for quite a long time, if a large amount of data on the clipboard. And having the data on the clipboard is mostly by accident. 

An example
1. Open https://yadi.sk/i/rM9QctDym5y3M
2. Copy the columns A-C
3. Close Calc -> Back to Start Center
4. Close LibreOffice -> Notice that LibO will run for 12 seconds in the background before it closes

So, "You have a large amount on the clipboard. Would you like to clear it?", , looks like a pretty obvious feature.

@Buovjaga, an opinion on this?

Ok, I believe you.

Bug 159272 has more illustrative of the sneaky aspect of the issue at hand: a 47 kb file causing 5 GB RAM spike with large range of data on the clipboard

I came here from just randomly testing Bug #132132 (same exact document Telesto just mentioned/referenced/duplicated with Bug #159272).

My RAM usage actually reached 7(!!!) GB—for 39 seconds after closing LO—when testing attachment 139120 [details].

So yes... if this clipboard-stuck-in-memory is the root cause of the issue, then definitely sounds like a good idea to have that:

- "You have a lot of stuff copied. Do you want to clear the clipboard?" warning on close.

(I recall seeing similar popups in Word and a few other programs too.)
