object allocation during garbage collection phase
Reported by georgiev | September 25th, 2008 @ 09:29 AM | in 3.x
I am experiancing random "object allocation during garbage collection phase" errors in rails app. I tried upgrading ruby and rails - the error persists with ruby 1.8.6_p287/1.8.7_p72 / rails 2.1.0/2.1.1. Also tried in different servers - mongrel and apache/mod_rails.
The error araises from random locations too. The most frequent one is "/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active_support/callbacks.rb:271"
Unortunately I have no idea how to make a relatively simple script to reproduce the error.
The attachment file contains two consecutive crash events in gdb session.

I realize I'm late to the party on this, but this is behavior we've seen at Pivotal a number of times now on a number of different projects. I've made the problem go away by updating to the latest version of RSpec in some cases, and updating to the latest version of LibXML in other cases. I have yet to see anything that indicates Rails is causing the bug to manifest.
Short mentions of this bug, and the havoc it has caused at http://pivotallabs.com/users/bri... and http://pivotallabs.com/blabs/arc... .

I managed to narrow down this to a bug in the firebird-adapter - leaking open result set objects.
In case someone else infected with the firebird-adapter bugs finds this - the attached file contains fix for that particular bug along with various fixes/enhancements from the Scott Knight patches. ;)

georgiev : Firebird related code doesn't really live in the core anymore.
Also, I don't think there is any point in keeping this ticket open unless the problem can easily be reproduced. Will reopen once we have a failing test or more details.
Thanks.
