Scraping is stopped even though I passed infinite as an argument

[abbrima]

I'm trying to scrape as much data as possible.
I'm sure there are more posts than what I'm getting, I got 1400 posts without comments and checking the last one's date, I found that it is relatively new (25 days old). Any idea why this occurs? Please note there is adequate ram in my computer and cpu usage never goes above 30%
