From: THAKUR PRASHANT SINGH on 26 Feb 2010 06:24 Thanks for help I think I got the issue solved. file = File.open("kml/#{@file_names[file_index]}","w") file.write(@kml_file_data.to_xml) file.close The last line was missing. When I closed the file the problem disappeared -----Original Message----- From: THAKUR PRASHANT SINGH Sent: Friday, February 26, 2010 4:48 PM To: ruby-talk ML Subject: Re: Class Function call vs Normal Function call Hi Brain, I have tried to create a test application with code like zip_file= ZipUtils.new('FILE_0.kml') zip_file.createkmzfile this works fine. The problem comes which I think is when we have very high CPU usage in my case it was 50% i.e. in dual processor machine a processor was completely occupied. Can this be a reason ? The test scenario can be load the CPU in program and then execute these lines when utilization reaches these levels. I got a similar issue when I was using REXML which got corrected when I switched to Nokogiri.. Any other pointers ??

As I said, you need to create two separate *standalone* test cases which replicate the problem. This is because the problem you describe makes no sense just with the code snippets you posted, since the code is the same in both cases, as you know. Hence the problem lies somewhere outside, and so it's up to you to provide two *complete* runnable programs which demonstrate the problem. Since these programs read external data, you'll need to provide some sample data files too (or better, include some short data items within the code itself, if you can still replicate the problem like this) -- Posted via http://www.ruby-forum.com/.

I will do the changes proposed. It indeed looks a good solution Thanks, Prashant -----Original Message----- From: b.candler(a)pobox.com [mailto:b.candler(a)pobox.com] Sent: Saturday, February 27, 2010 2:09 AM To: ruby-talk ML Subject: Re: Class Function call vs Normal Function call THAKUR PRASHANT SINGH wrote: > Thanks for help I think I got the issue solved. > file = File.open("kml/#{@file_names[file_index]}","w") > file.write(@kml_file_data.to_xml) > file.close > The last line was missing.
