Bug 358956

Summary:	Uses very much CPU while baloo_file_extractor forks itself
Product:	[Frameworks and Libraries] frameworks-baloo	Reporter:	Joseph O Morrow <josephomorrow>

Description Joseph O Morrow 2016-02-03 15:34:30 UTC

Current versions:

kf5-baloo-libs-5.18.0-1.fc23.i686
kf5-baloo-5.18.0-1.fc23.i686
baloo-libs-4.14.3-5.fc23.i686
kf5-baloo-file-5.18.0-1.fc23.i686
baloo-widgets-15.12.1-1.fc23.i686
baloo-akonadi-4.14.3-5.fc23.i686

Process baloo_file runs baloo_file_extractor. Then baloo_file_extractor forks itself. The new fork opens no files, but causes original baloo_file_extractor to over-use CPU. Process baloo_file then runs a apparently-bogus fork of itself.

Killing the forked baloo_file_extractor causes over-use of CPU to cease. Killing the forked baloo_file process causes all baloo_file* to stop altogether.

Reproducible: Always

Steps to Reproduce:
1. Log into Plasma 5


Actual Results:  
baloo_file_extractor begins to hog CPU as described in "details" above.

Expected Results:  
Nothing should be hogging CPU.

I have read about various "solutions", including blacklisting home folder, but all seem to just be workarounds that merely kick the can further down the road.

Used htop (tree mode) and ftop to monitor process behavior.

fedora 23

kernel: kernel-core-4.3.4-300.fc23.i686
