[Equest-users] Maximum number of tracked modifications exceeded

[Scott Criswell]

Hi Karen,

I am pretty sure that the "Maximum number of tracked modifications 
exceeded" error and simulation abort.  Though the error sounds fairly 
critical, it is really just an indication that a modification to the 
detailed model is causing so many cascading other changes and 
re-defaulting that the expression dependency and evaluation mechanism is 
unable to keep track of the history of those changes in memory.  All 
cascading changes however ARE evaluated and posted to BDL (despite this 
error message) and we have seen no cases where this error was an 
indication that the detailed model was in fact corrupt in some way.

If your model still aborts part way through the simulation, then I 
recommend you search through the .SIM output file for any occurrences of 
"ERROR" or to the end of the file which may provide an indication of why 
the simulation terminated.  If this doesn't lead to a solution, then 
feel free to forward me your project files (.pd2 & .inp compressed into 
a ZIP file) and I will take a look.
