BTW This is the PHP extension I used to get memory info of my objects: https://github.com/mathieuk/php-meminfo/tree/bugfix/use_correct_symbol_table_php71
andig
I have setup new Laravel application without any additional packages or service providers it seems like to be leaking memory on each request. I tried to collect some info using meminfo but that too is not able to provide relevant info:
Memory Leaks:
With each request it is adding around 2MB of memory and not releasing it. I generated the meminfo and it is reporting all well, here is the summary:
I dumped the above summary inside PHPPM\Bootstrap\Laravel@postHandle method
meminfo_dump(fopen('/tmp/my_dump_file.json', 'w'));I do not see any objects listed there which sounds strange to me unless I am misinterpretting it :(
