Seems to me that you are trapped in an infinite delta activation loop (-> delta 4949). 

Maybe there are two processes in your design activating each other without reaching a stable state.


To find such a problem, you can add print commands to the suspicious processes. Or you can activate ModelSim's profiler to analyze if there is any process consuming a suspicious amount of processing time.
