Tracker: corrupted index, high CPU
My only issue after an otherwise smooth upgrade to Ubuntu 9.04 (Jaunty) has been with Tracker. After logging in I noticed high disk and CPU usage, and eventually an error came up regarding corrupted index. I have tried several times to re-index, this did not work; also pausing all indexing in the tracker applet has no effect on the CPU usage by the trackerd process.
The error and solution are discussed in more detail on Ubuntu Forums. The following suggestion fixed the problem for me:
sudo apt-get install tracker-utils
tracker-processes -r
And then letting tracker rebuild the index at the start of next session. Note that the above command will remove all existing tracker files (this should not be a problem since they’re causing the issue in the first place) and that depending on how much data needs to be indexed it can take a while to recreate the index.
