[Apache & PHP] “zend_mm_heap corrupted” error on apache logs

2018-01-03 KENNETH 0

[Apache & PHP] “zend_mm_heap corrupted” error on apache logs   오류 내용 zend_mm_heap corrupted   발생 환경 OS : CentOS-7 WEB : apache-2.4 PHP : php-5.6   참고 : https://stackoverflow.com/questions/2247977/what-does-zend-mm-heap-corrupted-mean http://php.net/manual/en/internals2.memory.management.php   설정 FILE : $APACHE_HOME/bin/apachectl export USE_ZEND_ALLOC=0   절대적인 내용은 아니겠고, 이런 설정을 apachectl 에 한번 추가를 해보자…   PHP 메뉴얼에는 Note: USE_ZEND_ALLOC=0 in the environment will stop the memory manager from functioning, all allocations fall back on the default system allocators which can be useful for debugging leaks, and should only be used for this purpose. 이렇게 설명이 되어 있었다… ㅋㅋㅋㅋ
