I''ve only been on the list for a few days. I like what I''ve been reading. I thought I''d post here to learn if anyone else has experienced a similar issue? I seem to be having trouble with a production launch of Apache/Mongrel. The environment is * Apache2.2 with mod_proxy_balancer * Mongrel 1.1.3 * Windows 2000 advanced server This is the error I''m getting: Fri Feb 08 ... 2008: Read error: #<Errno::ECONNABORTED: An established connection was aborted by the software in your host machine.> c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/http_response.rb:137:in `write'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/http_response.rb:137:in `write'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/http_response.rb:95:in `send_header'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/http_response.rb:146:in `finished'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:165:in `process_client'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:285:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:285:in `initialize'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:285:in `new'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:285:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:268:in `initialize'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:268:in `new'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel.rb:268:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/configurator.rb:282:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/configurator.rb:281:in `each'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/configurator.rb:281:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/mongrel_rails:128:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32/bin/../lib/mongrel/command.rb:212:in `run'' c:/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.3-i386-mswin32 /bin/mongrel_rails:281 c:/ruby/bin/mongrel_rails:16:in `load'' c:/ruby/bin/mongrel_rails:16 It seems like the issue occurs when clients cancels their http requests either by navigating away from the page or clicking the stop button in their browser. This eventually causes Mongrel to hang when it''s coupled with Apache. I think it is only happening when Mongrel is behind Apache. I could run another stress test to confirm but I''m fairly certain that when Mongrel is not behind Apache it does not hang. It still throws the same exception "Errno::ECONNABORTED" but it is handled gracefully without hanging. When Apache sends requests by proxy then Mongrel hangs, even if ProxyPass is used instead of Proxy balancer. Also I noticed this morning that even after I end the stress test, mongrel keeps running processes/requests after the client has closed the connections. Thanks the excellent work that has produced an agile little server. Any input is appreciated even if it''s just something stupid like explaining whether I need to use keep-alives or not (and how).
