Subject: [ruby-talk:16333] Thread deadlock message - what does it mean?


I haven't gotten one of these for a while, here's the message:


deadlock 0xd7368: 2:2  - /usr/local/lib/ruby/site_ruby/1.6/drb/drb.rb:95
deadlock 0xde4c0: 2:1  - /usr/local/lib/ruby/site_ruby/1.6/drb/drb.rb:100
deadlock 0xd0228: 2:1  - /usr/local/lib/ruby/site_ruby/1.6/drb/drb.rb:304
deadlock 0x55f88: 2:1 (main) - /vobs/tests/gift/vhdl_pool/drink.rfl:1
Exception `fatal' at /vobs/tests/gift/vhdl_pool/drink.rfl:1 - Thread:
deadlock
/vobs/tests/gift/vhdl_pool/drink.rfl:1: Thread: deadlock (fatal)
        from nogapok:93:in `load'
        from nogapok:93
        from nogapok:86:in `each'
        from nogapok:86
        from nogapok:80:in `each'
        from nogapok:80

How do I interpret the 'deadlock 0xd7368: 2:2' (I imagine that the
'0xd7368' is the thread id, but I don't know what the '2:2' part means)?


What can I do to avoid this sort of thing?
(this is an application that uses dRuby 1.3.1)
The message above is from a machine running Ruby 1.6.2 on Solaris.
