Continuous "undefined method `delete' for nil:NilClass" log entry

[PavelKovalets]

Hi, I'm using dea_ng, installed with the help of Installation package. But when I'm trying to resolve some issues there is a log message in
c:\IronFoundry\log\dea_ng files that appears every few minutes:

{"timestamp":1374840708.354184,"message":"varz error #<NoMethodError: undefined method delete' for nil:NilClass> C:/Ruby193/lib/ruby/gems/1.9.1/bundler/gems/vcap-common-01eddc88406b/lib/vcap/component.rb:104:in updated_varz'\nC:/Ruby193/lib/ruby/gems/1.9.1/bundler/gems/vcap-common-01eddc88406b/lib/vcap/component.rb:23:in call'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/rack-1.5.2/lib/rack/builder.rb:138:in call'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/rack-1.5.2/lib/rack/urlmap.rb:65:in block in call'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/rack-1.5.2/lib/rack/urlmap.rb:50:in each'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/rack-1.5.2/lib/rack/urlmap.rb:50:in call'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/rack-1.5.2/lib/rack/auth/basic.rb:25:in call'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/thin-1.5.1/lib/thin/connection.rb:81:in block in pre_process'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/thin-1.5.1/lib/thin/connection.rb:79:in catch'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/thin-1.5.1/lib/thin/connection.rb:79:in pre_process'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/thin-1.5.1/lib/thin/connection.rb:54:in process'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/thin-1.5.1/lib/thin/connection.rb:39:in receive_data'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/eventmachine-1.0.3/lib/eventmachine.rb:187:in run_machine'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/eventmachine-1.0.3/lib/eventmachine.rb:187:in run'\ndea_winsvc.rb:40:in service_main'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/win32-service-0.8.0/lib/win32/daemon.rb:300:in mainloop'\nC:/Ruby193/lib/ruby/gems/1.9.1/gems/win32-service-0.8.0/lib/win32/daemon.rb:202:in mainloop'\ndea_winsvc.rb:69:in

It floods my log file and I cannot read it. How can I fix that?

I ran into the same problem as yours, also using the installation package.
The reason is that ruby tries to execute a "tasklist" command to fetch the PID for dea_ng, but gets nothing returned (in fact, the "tasklist" is not executed at all. I don't know why.)
The newest codes have fixed this problem. So you should try the "install by scratch" way.
