What is maximum number of scripts allowed on stack? Is it possible to change?

I use the free version.

I was scraping data from http://yellowpages.superpages.com/listings.jsp?C=apartments&CS=L&MCBP=true&search=Find+It&SRC=&STYPE=S&SCS=&channelId=&sessionId=

The session was working just fine and after some 50 pages of scraping, I got an error saying something like this

ERROR--halting the scraping session because the maximum number of scripts allowed on the stack was reached. Current number on the stack is: 50.

What does it mean? In the place of 124469 records in total I got some 1400+ records. How can I get all the data scraped?

I really need some help here.

Thank you.

You can change that limit,

You can change that limit, but you don't want to. I think you need to review this post to get you through it:
