ArrayInitialize function internal error

 

What does this mean and how can I tell which ArrayInitialize call is failing in my code?

 
The one that is trying to initialize an indicator buffer.
 

No, i'm pretty sure i removed all those when i turned my indicator into an EA. It also only occurs between 22:00 and 00:00 server time. the EA still keeps going and trading, though. Weird!

 
put a Print() in front of every ArrayInitialize() and then let it run until it happens again.
