I am using LibreOffice

Version: 6.0.7.3 Build-ID: 1:6.0.7-0ubuntu0.18.04.10 CPU-Threads: 12; BS: Linux 4.15; UI-Render: Standard; VCL: gtk3;

on an Ubuntu 18.04 LTS. When copying something, the system freezes for a couple of minutes. When running top in console before copying, i can see process gjs on 100% cpu and using all RAM and Swap. System needs several minutes then runs smoothly again. kern.log shows this:

Jan  8 19:29:54 Ubuntu-Desktop kernel: [ 2069.787482] gjs[11334]: segfault at 0 ip 00007efd97fd7258 sp 00007ffc9c1d8a80 error 4 in libgjs.so.0.0.0[7efd97faf000+c7000]

In Writer this only happens every 10th time or so, but in Calc every single copy-action triggers this. Nautilus also frequently triggers this bug when pasting files, with same symptoms occuring.

I am not sure how to proceed from here. Any suggestions? Thanks in advance!

  • Edit your question and show me free -h and sysctl vm.swappiness and sudo lshw -C memory.

Consider disabling GNOME Extensions. In my case the culprit was GSConnect
