[Gems-users] Ruby Crashing in Sequencer

[Mrinmoy Ghosh <mrinmoy@xxxxxxxxxxxxxx>]

Hi,
        I am trying to run the mcf benchmark of SPEC in simics with 
ruby. The OS used is suse-linux on Sparc(Bagle). Simics crashes giving 
the  message attached at the bottom.
This possibly happens because some memory request resided in Ruby's 
Sequencer queue for more than a 100000 cycles(I set the deadlock 
threshold at 100000). Can anybody give me a clue as to why this may be 
happening?
