Description rimrunner 2020-09-06 12:33:03 UTC
Description:
After some time (15 minutes to half an hour?) soffice.bin process starts to eat 100 % of cpu time (as seen with UNIX's top utility). It stops after I save a document that is open. Autosave does not stop it, only the save command from the user.

The problem appears even if the user just starts an empty write document and waits long enough (also if older document is opened). I have not any special settings turned on.

LibreOffice version: 6.1.5.2. Kernel 4.19.118 hardware: Raspberry Pi 4, 4 GB OS: Raspbian (Raspberry Pi OS), 32-bit, based on Debian buster

Exactly the same problem appeared on IBM T43 computer with Slackware 14 (32-bit cpu, 2 GB mem) and a bit older LibreOffice version.

The problem didn't appear with Lenovo Thinkcentre M55 (a desktop computer released in 2006) and Debian. It looks anyway that the problem appears with some older systems (so far they all have had 32-bit OS though RPi4 is a 64-bit computer, typically running in 32-bit mode).

Steps to Reproduce:
1. Start LibreOffice Writer in a system where the bug appears
2. Wait for 15 minutes to half an hour or so while keep on watching CPU usage
3.

Actual Results:
office.bin process eats all the CPU that is available

Expected Results:
Writer without activity should not use barely any CPU


Reproducible: Always

LibreOffice 6.1 isn't outdated and not supported anymore; Please use 6.4 or ideally even LibO 7.0
Comment 2 rimrunner 2020-09-06 15:16:05 UTC
Sadly, the version I'm using is the latest that can be found from Raspberry Pi OS's repository

Set to NEEDINFO accordingly.  rimrunner: Please set back to UNCONFIRMED if this bug exists in the newer supported version. Without this information we are not able to identify the issue, especially it's on Raspberry Pi and maybe not on other linux distributions.
