A lot of Zombe pigmen go thorugh portal over a short period of time

So I was standing in my base AFK fishing on my server. After around 2 hours I check the console and see that the server is running around 30k-50k ms behind (~1000 ticks behind). When I go back to my minecraft game to see what is going on I see a **plethora of zombified piglins around my base. In previous versions only 1-3 would go through, not this many. Here's a video showing my findings: https://youtu.be/t5lkFOiehT8  Since the server crashed, most likely due to this, I've also included the server crash report text file.
