我的系统日志中收到很多奇怪的 suhosin 警报。以下是示例条目：
Jun 9 08:46:11 suhosin[9764]: ALERT - script tried to increase memory_limit to 2145386496 bytes which is above the allowed value (attacker '157.55.39.180', file '/var/www/site/index.php')
Jun 9 08:46:11 suhosin[9744]: ALERT - script tried to increase memory_limit to 2145386496 bytes which is above the allowed value (attacker '109.74.2.136', file '/var/www/site/test.php')
Jun 9 08:46:13 suhosin[9779]: ALERT - script tried to increase memory_limit to 0 bytes which is above the allowed value (attacker 'REMOTE_ADDR not set', file 'unknown')
Jun 9 08:46:13 suhosin[9779]: ALERT - script tried to increase memory_limit to 2145386496 bytes which is above the allowed value (attacker 'REMOTE_ADDR not set', file 'unknown')
这里发生了什么？为什么是 0 字节或 2145386496 字节（2046 GB！！？？）？为什么它有时会显示攻击者和请求的脚本，有时会显示“REMOTE_ADDR 未设置”和文件“未知”？我该如何继续解决这个问题？
