Ruby/programming noob here. I’ve just finished my first real app, but  
it’s  
performance is occassionally plagued by the following error message:

c:/ruby/lib/ruby/1.8/timeout.rb:54:in `rbuf_fill': execution expired (Timeout::Error) from c:/ruby/lib/ruby/1.8/timeout.rb:56:in `timeout’  
from c:/ruby/lib/ruby/1.8/timeout.rb:76:in `timeout' from c:/ruby/lib/ruby/1.8/net/protocol.rb:132:in `rbuf\_fill’  
from c:/ruby/lib/ruby/1.8/net/protocol.rb:116:in `readuntil' from c:/ruby/lib/ruby/1.8/net/protocol.rb:126:in `readline’  
from c:/ruby/lib/ruby/1.8/net/http.rb:2017:in `read_status_line' from c:/ruby/lib/ruby/1.8/net/http.rb:2006:in `read\_new’  
from c:/ruby/lib/ruby/1.8/net/http.rb:1047:in `request’

I did find one proposed solution here (modifying the rbuf\_fill method):  
[Timeout errors using Net::HTTP on Windows - Ruby - Ruby-Forum](http://www.ruby-forum.com/topic/105212) , but it doesn’t seem to work for  
me. These posts also explains why standard error handling won’t work.

Does anyone have another solution?

Thanks a bunch!

Timeout::Error is an Interrupt subclass, which is not a StandardError  
subclass. You must rescue Timeout::Error explicitly to handle the  
exception.

I didn’t understand what you meant at first. Once I had some time to  
look  
into explicit exception handling I figured it out, and it worked -  
thanks!
