Problem random

 
I have an indicator loaded on 13 assets, each tick processes a series of data in D1, H4 and M30.

In 10 MT4 the behavior is the same but a MT4 inside VPS did not perform a certain passage.

Is it possible that with all these assets the memory of the MT4 fills up generating a block "momentarily even 30 minutes?

P. S.: Broker and Server is same for all MT4
