LibreOffice 6.2 freezing

LibreOffice freezes very often. Or perhaps it would be fairer to say that Calc does – I’m not really sure about Writer – but when it happens, my only option is to kill the whole LibreOffice, Writer and Calc windows alike, and then hope that the last autosave took place recently enough. I have the impression that this tends to happen when I hit two keys in very close sequence, as if the system were unable to catch up with my fingers. But such a thing is not believable, is it?
I run LibreOffice (a supposedly stable version) under Linux Mint 19.1, desktop Cinnamon 4.0.10, with 8Gb RAM.
Have people noticed such a thing? Is there anything I can do to diagnose the situation when it occurs, handle it with less damage than killing LibreOffice does, or prevent it?

You could try updating through flat pack the version there is That was the only solution that I found to it when it froze. Just do a back up before doing so, and then uninstall the present version or you’ll have two versions.
I would also suggest that you upgrade to Mint 19.2 which you can do through Update Manager.
Sorry don’t have another solution that I know will work apart from these suggestions


I also have the same problem of freezing. I was using Ubuntu Mate, 8GB RAM, LibreOffice 6.2. While using LibreOffice and open many firefox tabs, the system monitor shows the RAM and Cache use 100% and then freezes. I search for a solution, finally I added an 8GB RAM (now total 16GB RAM) and solved the problem successfully. I think there is no other way to solve this problem. (Now updated to LibreOffice 6.3)

Hi and welcome to our community.
As I said in my reply early the only way around it I found was to do the update as you have done- no other solution seemed to work - I don’t know why

Upgraded both the system to Mint 19.2 and LibreOffice to; let’s see how it will go.

P.S. No, that was useless. LibreOffice is frozen. Seeing that the memory was all full (mostly taken by some heavy web pages), I killed FireFox. After that System Monitor reported that the memory was 75% free, but LibreOffice was (and is) not responding. (‘You may choose to wait a short while for it to continue or force the application to quit entirely.’—the ‘short while’ is looking as though it will never end.)


Indeed, the programs mentioned are extremely RAM hungry. And depending on the version, a memory leak could cause even higher RAM usage. I remember an old Firefox version from about half a year ago, that had a huge memory leak… Finally it is fixed, though.


Right Akito, Firefox using 3.2 GB Ram 1.4 GB RAM by LibreOffice and Cache 3.5 GB Ram total of 8.1 GB of 16 GB
