[Threshold]

That shouldn't really matter. The only difference is that the first one gives you access to listitem 5.

Try using:

PHP код:

new bigstring[1655]; 


The maximum length you can have in the max dialog text is 4096. So using a string size of 6000 is unnecessary.

Never really encountered this issue before, but it could possibly be because you're using an array of 6000?
