[Tracker] ERROR: Inotify watch on ... has failed

[Johann Petrak <johann petrak chello at>]

I have Tracker running since my upgrade to Ubuntu Gutsy for several
weeks now. It is configured to index my home directory and another
directory.

However, none of my queries ever returned even a single hit.

I ignored this since I am using Beagle, which works well.

Today I wanted to test Tracker again and after some experimenting I
killed trackerd and invoked it from the console using:
  trackerd -v 2

This shows, among other messages:

...
Setting inotify watch limit to 8191.
Watching directory .... (total watches = NNN)
...
ERROR: Inotify watch on <dirname> has failed
ERROR: Inotify watch on <dirname> has failed
(many more)

Then, nothing seems to happen anymore.

I did not find a way to change that limit 8191, and I definitely
have several tens of thousands of directories in my home directory.
Even if I exclude some that are not that necessary to have
included, I will remain with mar more than 8191.

So my questions: is my assumption correct that this problems
prevents Tracker to index/find anything interesting?
And how can I correct the problem?
