SUMMARY
baloo_file_extractor fills swap space even though there's plenty of RAM
available.
STEPS TO REPRODUCE
1. Verify that file search (including file contents) is enabled and that the
files have been indexed.
2. Check RAM and swap file usage. If there's plenty of RAM available and swap
usage is couple of GB try following steps.
3. Open System activity (CTRL+ESC) and stop baloo_file_extractor (right click
on baloo_file_extractor and go to Send signal -> STOP).
4. Remove swap file (swapoff -a)
5. Mount swap file (swapon -a)
6. Verify that swap usage is around 0%.
7. Resume baloo_file_extractor (Send signal -> CONT)
8. Monitor swap file usage. It should go up very quickly after you resume
baloo_file_extractor.
OBSERVED RESULT
After starting or resuming baloo_file_extractor swap file usage goes up very
quickly although there's plenty of RAM available.
EXPECTED RESULT
baloo_file_extractor should use RAM if it's available and use swap only if
there's no RAM available
