Is there a limit on the size of an array in ruby? [duplicate]

Array size too big - ruby

Sorry if this has been asked, I looked around but didnt really find what I was looking for.

I am using ruby and mysql to create an array based off of a single column in the mysql table. So for example, say I have a column of user names:

 users = []
 users.clear
 
 # Update the list of users to follow
 res = dbh.query("SELECT user FROM usernameDB")
 while row = res.fetch_row do
   users << row[0] #adds each user to the array
 end

This has worked fine up until now, when we started recieving a lot more users. Now the code gives me unknown errors.

In an attempt to troubleshoot, I simply commented out most of it and built the array with just a couple of user names, and everything worked again. So my question is, is there a limit to the number or items in a ruby array?

Thanks!

Take a look at this other post: Array size too big - ruby. The size of 600 million was too big, but 500 million worked.

How big of an array are you working with? The problem may be that you're running out of memory!
