PHP：使用带内存的Pthread池的问题

Question

I have big Problem my server's 16Gb RAM

$scan_pol = new \Pool(2000);
$range = ip_range($start_range, $last_range);
foreach ($range as $ip_num => $ip_value) {
    $scan_pol->submit(new scan($ip_value));
}

I submit in $scan_pol 16581375 Task

unset($range);
while ($scan_pol->collect()); // here i want to edit
$scan_pol->shutdown();

and while I see the Performance in Task Manager the memory usage Excessively increasing to full and popup this error snapshot

then stop CLI
I want while collect Tasks delete task from memory to balance memory usage

NOTE: I changed Pool Threads 2000 to 1000
and tried to Reduce $range Array To reduce the pressure on the RAM but same problem

because collect after Terminated Task don't unset it from memory

Any help please

Thank You

You can implement your ip_range function as a generator instead of an iterator, which will save you a lot of memory overhead. look here:http://php.net/manual/en/language.generators.overview.php

It can be used directly in a foreach loop without assigning a value to a variable.

Then, please set the size of your pool according to your memory size.

I hope this will help you.
