我在电子商务网站遇到一个非常奇怪的问题：更新订单状态的一些查询（但不是全部）因某些神秘原因而失败。
在客户成功付款后，支付网关会调用在线商店中的php脚本，该脚本应更新相应订单的状态（从“待处理”到“已确认”）。
这适用于某些情况，但不适用于其他情况。我注意到当从特定的IP（和相应的端口）调用回调URL时，order_status_update（）的模式是有效的，而不是从另一个IP调用的。
我已经完成了代码并使用一堆日志记录对其进行了检测，并且所有内容都检查到了查询级别，但在一种情况下它可以正常工作，另一种情况则是失败。
我能看到的唯一区别是：
1）服务器的IP调用回调脚本，
2）服务器的远程端口调用回调脚本。
据我所知，调用的$ _SERVER ['REMOTE_ADDR']不应对执行的任何内容产生影响（除非脚本显然做了相应的事情，但事实并非如此），所以我'我想知道$ _SERVER ['REMOTE_PORT']是否会对MySQL /数据库产生影响，导致查询可能失败？
当脚本/查询成功时，REMOTE_PORT为18436，当它失败时，REMOTE_PORT为49495。
我已经从两个订单附加了日志记录，第一个是成功的，然后是第二个失败 - 你可以看到它们实际上是相同的（除了order_id和mdate，正如预期的那样）
什么时候有效：
nab_notify - 使用d [] =调用order_status_update：数组\ n（\ n [order_id] =＆gt; 2860 \ n [order_status] =＆gt; C \ n [notify_customer] =＆gt; Y \ n）\ n
ps_order :: order_status_update - d [] =数组\ n（\ n [order_id] =＆gt; 2860 \ n [order_status] =＆gt; C \ n [notify_customer] =＆gt; Y \ n）\ n
ps_order :: order_status_update - curr_order_status：order_status：C notify_customer：1
ps_order :: order_status_update - UPDATE vm_orders（1）w / fields [] = Array \ n（\ n [order_status] =＆gt; C \ n [mdate] =＆gt; 1314093024 \ n）\ n
ps_order :: order_status_update - UPDATE vm_orders（2）order_id：[2860]
ps_order :: order_status_update - UPDATE vm_orders（3）QUERY：[UPDATE #__vm_orders SET order_status ='C'，\ n mdate ='1314093024'\ nWHERE order_id ='2860']
ps_order :: order_status_update - UPDATE vm_orders（4）qresult：[1]
当它不起作用时：
nab_notify - calling order_status_update with d[]=:Array\n(\n [order_id] => 2863\n [order_status] => C\n [notify_customer] => Y\n)\n
ps_order::order_status_update - d[]=Array\n(\n [order_id] => 2863\n [order_status] => C\n [notify_customer] => Y\n)\n
ps_order::order_status_update - curr_order_status: order_status:C notify_customer:1
ps_order::order_status_update - UPDATE vm_orders (1) w/fields[]=Array\n(\n [order_status] => C\n [mdate] => 1314137858\n)\n
ps_order::order_status_update - UPDATE vm_orders (2) order_id:[2863]
ps_order::order_status_update - UPDATE vm_orders (3) QUERY:[UPDATE `#__vm_orders` SET `order_status` = 'C',\n`mdate` = '1314137858'\nWHERE order_id='2863']
ps_order::order_status_update - UPDATE vm_orders (4) qresult:[0]
鉴于“相同”的查询，有人可以解释为什么一个人会失败而另一个人会成功吗？
谢谢， 埃里克
更新1：我添加了查询级别日志记录并发现了一些错误，日志显示：
ERROR 2006 - MySQL服务器已经消失
...但奇怪的是并非在这个特定会话中的所有查询（猜测这是令人鼓舞的？）。我留下了痕迹中的断线，以防它们有一个方位。
我经过几次搜索和其他论坛帖子后，检查了php设置并查看
max_execution_time = 60
max_input_time = 60
应该有足够的时间吗？
奇怪的是，只有当从特定IP（与其他订单状态未更新时相同的IP）完成对特定URL的请求时，才会出现这种情况。
