Tried to find similar issues, but missed 33487 ticket. Is there any way in cli enviroment to free all unused memory? (Beside restarting the process). Sometimes a process, which runs one or two week in a row can consume 500+ MB of RAM.

The object store will use 8 bytes * next_power_of_two(max_number_of_objects_alive_at_the_same_time). Because object store buckets are reused when objects are destroyed, you usually do not need to worry about this. It's a one-time cost of creating many objects, not a leak that will be incurred for every object. ------------------------------------------------------------------------ [2018-09-14 14:56:59] toma dot zoltan at bitninja dot io Description: ------------ I have a long running daemon script, which could create thousands of object every 5 minutes. I tried to free them, but memory was still used by the process. An example script: https://3v4l.org/5ap4Z It doesn't matter if class is empty. Or one or multiple class instances are used by the test. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76883&edit=1
