--- Comment #19 from Patrick Luby (volunteer) <guibomac...@gmail.com> --- I have a new guess as to what might be causing the system crashes: one or more clipboard history applications are using up most of system memory. After fixing tdf#160855, we now know that one or more clipboard history applications are pasting immediately after copying in Calc and, if you frequently select and copy hundreds of thousands of cells, the data formats that Calc sends to the system clipboard get very large. See my following comment for more background info: https://bugs.documentfoundation.org/show_bug.cgi?id=160855#c26 To test this, would it be possible for you to run the Activity Monitor application in the background but this time with the search field empty? This will display all applications running on your machine. Set the Memory column to sort highest to lowest like shown in attachment #194039. Then, launch LibreOffice and select 100000+ cells and copy. Repeat this with different cell ranges at least 10 times, get a screen snapshot of the Activity Monitor window, and attach it to this bug? If 10 times causes a system crash, retry but only half the number of times. If one or more clipboard history applications have the highest memory usage, we can check if those applications let you lower the maximum history size. -- You are receiving this mail because: You are the assignee for the bug.
