Maaaybe. The Results and Logger workers get started when you start
backgroundrb w/ "script/backgroundrb start", long before you create a new
worker (or even start rails). Then again, the Results and Logger workers
are mostly just regular workers that get initialized the same way as other
workers, so they may be getting 'lost' in the same way? Not sure!
You may want to try the 'end.join' fix that skaar just checked in (
I believe should fix at least the problem I originally described:
In vendor/plugins/backgroundrb/server/lib/backgroundrb/middleman.rb, just
change the closing 'end' of the '@thread_pool.dispatch do' block to '
You're not seeing "In ResultsWorker" in backgroundrb.log. Are you using
release-0.2.0, or are you working from the trunk? What do you see when you
ps aux |grep backgroundrb
Maybe you're assigning to the results hash incorrectly? If you're doing
something like the following, it won't work (see the README):
results[:other_key] = 
results[:other_key] << "add to key"
