After running TESTDISK i got a lot of files with name Fnnnnn.ODS and .ODT
Openning one looking what is in and for some SAVE AS xxxx, then CLOSE DOCUMENT (not application) and after delete the Fnnnnn.ODS (or ODT) and open the next one.
After 7 to 10 documents CENTOS FREEZES just the mouse is moving but nothing else works, even the clock doesn’t change, the only possibility was to POWER OFF.
Doing the same thing but CLOSING THE APPLICATION for each document solves the problem.
The version i have is :
Build ID: 22.214.171.124-19.el7
Threads CPU : 4; Version de l’OS :Linux 3.10; UI Render : par défaut; VCL : gtk3; Moteur de mise en page : nouveau;

Many thanks for your help,
