Application

Composer

Operating system

Linux

Current behavior

will stop at some points
222795/222801 [===========================>] 99% -- 23 failures

Expected behavior

Finish successfully

Steps to reproduce

I believe it happens when we use multiple threads option, I was running with 100 threads.

Additional context

The problem doesn't happen all time but quite often, number of URL left are always small (just a few - less than number of threads). I believe when running multiple threads, something is wrong with calculation for some last URLs.....
(there is no output in the log file except logs for failures)
