[Gems-users] Deadlock deteced in the start of simulation with ruby

["Shachar Gang" <shacharg@xxxxxxxxxxxxx>]

Hi,

I am trying to write new cache protocol based on the broadcast protocol.
After loading a checkpoint and ruby module (with the right init parameters), 
when trying to continue the simulation I get the following error messages:

***  Simics getting shaky, switching to 'safe' mode.

Can anyone help my what can be the problem?
