I have a txt file with some data that i need to import to de database.  
I’m using ruby to import those data but i have a major problem, when i  
've  
a large amount of data i run out of memory.

File.open("#{RAILS\_ROOT}/public/files/Neighborsville.TXT").each() do  
|line|  
@stringArray = line.split("|")  
@i += 1  
puts @i  
@pid = @stringArray[0]  
@chain\_id = @stringArray[1]  
@business = Business.find\_by\_pid\_and\_chain\_id(@pid,@chain\_id);  
#Check PID + CHAIN\_ID  
@business.pid = @stringArray[0]  
@business.chain\_id = @stringArray[1]  
@business.cityname = @stringArray[17]  
@business.state = @stringArray[18]  
@business.business =  
Business.find\_by\_pid\_and\_chain\_id(@pid,@chain\_id);  
@business.city = City.new  
@business.business\_category = get\_category\_id(@stringArray[40])  
@business.address = @stringArray[8] +" “+ @stringArray[9] +”  
“+ @stringArray[10]+” “+ @stringArray[11] +” “+@stringArray[12]+”  
“+@stringArray[13]+” "+@stringArray[14]  
if @chain\_id == nil  
@chain\_id = “”  
end  
business.save  
end  
end

I belive that ruby use in every cycle of the do new blocks of memories  
por my instances  
of Business. Can someone help me please?

Thanks,

Probably not related, but should business.save at the end there be  
@business.save?
