Hi, my mongrel has crashed with following errors in the logfile: ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reload (without restart). It might not work well. ** Mongrel 1.1.3 available at 0.0.0.0:3000 ** Writing PID file to ./script/../config/../tmp/pids/mongrel.pid /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/core_ext/module/inclusion.rb:4: [BUG] gc_sweep(): unknown data type 0x0(0xa8b2241c) ruby 1.8.6 (2008-03-03) [i686-linux] Rails 1.2.6 What''s wrong? My system is too important to hang up in so stupid way and it''s too late to choose something different than rails.. m.

Something triggered an error that the Ruby interpreter thinks is a bug in the interpreter. Did this happen just once, or are you getting it often? Do you have anything monitoring the mongrel processes so that if they do go away, they can be restarted? Kirk Haines

Maybe also there''s new ruby. It happened from time to time, e.g. once for 3-4 weeks with my previous mongrel version (1.0.x). So I''ve made an upgrade to 1.1.3, but it worked only for 2 weeks. I don''t use any plugins in my rails app. I''ll come back if it remained with 1.1.4 Thanks, -- m.

My suspicion is that something that you are using has an extension in it that is doing something which interacts poorly with Ruby''s GC code. Which version of Ruby 1.8.6 is it that you are running? Make sure you are using the latest patch level of 1.8.6. This is very important. Kirk Haines

It still crashes... :( /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active_support/core_ext/module/inclusion.rb:4: [BUG] gc_sweep(): unknown data type 0x0(0xac53841c) ruby 1.8.6 (2008-03-03) [i686-linux] Once, there was a crash message related to gettext, but I''ve made an upgrade and it crashes like that. How to trace or debug that? m.

Since you''ve gotten the same identical exception twice, start there. It''s in ActiveSupport, not Mongrel, BTW. Here''s the line in question: ObjectSpace.each_object(Class) { |k| classes << k if k.included_modules.include?(self) } This is an interesting place for that error to occur. I don''t have an immediate hypothesis, but somehow something is getting into the Ruby heap that isn''t a recognized node type. Kirk Haines
Do you have any GC patches in Ruby, use of DL, shaky C libs, or a weird Ruby patchlevel?

Some things to try: Downgrade Ruby to p111 (unlikely). Avoid using gettext (more likely). Are you using any RubyInline plugins or vendorized gems?

I saw that, so I mentioned gettext as the only one that stands out. There can be more gems than just system gems though.

ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-linux]
I have 2 versions of gettext, I''ll try to uninstall older one, and if
it
won''t help, the newer one.
I have latest patchlevel of ruby, only custom patches could be from
gentoo''s portage.
It happened a few times before I''ve started to use gettext, but my
mongrel
was also older. Arghh seems to be difficult to find, what''s going on.
I''ll
try to do this gettext stuff...
