[Rubycocoa-talk] Help tracing a bug

[Javier S. <jav...@ri...>]

Hi All,

I've got an application that continuously polls values from several  
servers launching threads via a timer (ruby threads) that get the  
value and die and refreshing a window when new data is available. The  
refreshing is done with bindings. The app works ok for some time but  
eventually it crashes. The app is using ruby arrays and dictionaries  
(which hold numbers and strings) and I relay on the bridge to provide  
the GUI with Objective-C versions

This is the stack trace. The biggest problem is that I don't even  
know how to start debugging this problem, nor how to get useful  data  
for the development team.

Any tips on how to tackle this will be appreciated.
