I found that bumping up the older “Memory” settings, resolved a very consistent crash which occurs when I edit some drawings–which are not very large.
Once I make these changes, I no longer see the crash issue and LibreOffice seems to run faster. It remains perfectly stable for me now.
The settings I use currently under Options - LibreOffice - Memory are:
Use for LibreOffice: 200 MB
Memory per object: 10.0 MB
These Memory settings, above correlate exactly to the following Advanced attributes in byte count values below:
Options - LibreOffice - Advanced - Expert Configuration - org.openoffice.Office.Common - Cache - Graphic Manager
TotalCacheSize 209715200 (bytes) (same as 200MB above)
ObjectCacheSize 10485760 (bytes) (same as 10.0MB above)
I do not believe these particular values are specifically optimal, only that they are significantly higher than the default values provided before making the changes. Adjust them as needed for your own needs, I wanted to show the relationship between the old “Memory” and now “Advanced” settings.
