I am running jruby (1.7.3) & rails 2.3.17 application whose apis are
exposed to outside app. When I add "config.threadsafe!" in my
development.rb/production.rb & hit lot many api requests in a second then I
am getting following errors randomly for some of the api requests:
1. TypeError (NilClass can't be coerced into Float)
2. RuntimeError (can't add a new key into hash during iteration)
3. Rendering /appl/mml/tomcat/server/mml-api1/webapps/api/500.html (500
Internal Server Error)
4. Status: 500 Internal Server Error
Does newer jruby version solves this issue? But my application does not
support jruby > 1.7.3.
Also even if I add the affecting method in below synchronize block then
also it is not synchronizing that method. Note : I have added
"config.threadsafe!" in my development.rb & production.rb
semaphore = Mutex.new
thread = Thread.new {
semaphore.synchronize {
#affecting code/method
}
}
But if I remove "config.threadsafe!" from my development.rb/production.rb &
hit huge number of requests I am not getting any error but this time
performance is impacted.
Is there any solution to remove these errors without affecting the
performance?
