Error in FSM method

Questions
#1

I tried to calculate FSM, but i ended up an error

Q-Chem fatal error occurred in module 0, line 59:

** crntIShl .ne. lastIShl.**
I’m unaware of this kind of error. Could you please give some suggestions on how to sort it out?
Thanks in advance!

What version of Q-Chem are you using? Can you please also attach the end of your output? With Q-Chem 6.2, this job crashes after 200 iterations with the following:

STARTING FREEZING STRING ITERATION # 200
 The distance between the innermost nodes (Angstroms): 0.452
