Or if you're running memcached, restart it.

I found the same problem when I upgraded my local OBS instance from 2.0.5 to 
2.3. The /monitor page would show that builds were running for more than 32+ 
hrs, whereas, on the backend, no real jobs were running - /srv/obs/jobs/<arch>/ 
was empty.

I later found out that in 
/srv/www/obs/api/app/controllers/status_controller.rb, "workerstatus" is 
written to cache without any expiry timeout.

To solve this, in my local instance I changed the following code:

$ diff -u /tmp/status_controller.rb 
/srv/www/obs/api/app/controllers/status_controller.rb
--- /tmp/status_controller.rb   2012-03-19 21:18:13.000000000 +0530

     data=REXML::Document.new(ret)
 
     mytime = Time.now.to_i
-    Rails.cache.write('workerstatus', ret)
+    Rails.cache.write('workerstatus', ret, :expires_in => 20.seconds)
     data.root.each_element('blocked') do |e|
       line = StatusHistory.new
       line.time = mytime

Things have been better since this patch.

Hope this helps,
Srinidhi.

PS: there is one more Rails.cache.write in helpers/status_helper.rb without any 
:expires_in field. I haven't changed it because I haven't seen any problems so 
far with querying jobhistory.
