If turn on nginx debug log
./configure --with-debug ..., but not selectdebug_httplog level.ngx_log_debug1(NGX_LOG_DEBUG_HTTP, ...) will be ignored, malloc_trim() can't be executed as function parameter.
And memory isn't returned to OS immediately. This bug may cause serious memory leak, OOM.
Simply,
ngx_log_debug1is optional, butmalloc_trimobligatory.
