For example The crash occurs in-between opt cycles
Diag has

Exit Loop TA-Lib Series
Parameter 4 step 7: 11.44 => 0.90 1634/1927
StepCycle: 7
Quit

The Quit represents a crash during the time Zorro was trying to get a reading for Step 8. It hasn't begun executing Step 8 yet. I know this because there the INITRUN sends an RPC.
