soffice headless on server consumes 100% CPU

Hello,

if I call the headless mode:

# /usr/lib/libreoffice/program/soffice  --headless --nologo --norestore
 --accept="uno:socket,host=localhost,port=2083;urp" &

then the computer needs all its power for that software. top shows 100%
and the fans working hard.

What is wrong with this mode?


# soffice --version
LibreOffice 6.0.7.3 00m0(Build:3)

#  uname -a
Linux ws24 4.18.0-17-generic #18~18.04.1-Ubuntu SMP Fri Mar 15 15:27:12

Thank you in advance
