我有一台运行 DHCP 服务器的 Windows Server 2012 系统。尝试停止该服务需要 1 个多小时才能完成。它C:\Windows\System32\dhcp每天都会写入 GB 的 .LOG 文件（目前大小约为 16 GB）。
有人见过这样的问题吗？如何解决？
DHCP 服务器区域的 Windows 事件日志查看器中没有出现任何事件，因此我不确定这些文件到底是什么。它们是二进制文件，其名称如下：
j5000A1C.log
j5000A1D.log
每个以首字母 j 开头的文件大小为 1MB，总共约有 16GB。
还有一些人类可读的日志，包括今天的两个日志，我展示了其中的片段：
这似乎是今天的 DHCP-for-ip-v4 日志的活动：
ID,Date,Time,Description,IP Address,Host Name,MAC Address,User Name, TransactionID, QResult,Probationtime, CorrelationID,Dhcid,VendorClass(Hex),VendorClass(ASCII),UserClass(Hex),UserClass(ASCII),RelayAgentInformation.

我真的很困惑这些“j.log”文件到底是什么。
我同时运行着 ipv4 和 ipv6 DHCP 服务器，但是 ipv6 服务器没有配置任何选项。这意味着我看到没有选中任何复选框，所以我猜测，DHCP-for-ip-v6 的 100% 默认选项：
DHCP 服务器似乎处于“失控列车”模式，重新启动服务使其停止执行上述操作。但是我想知道是什么原因造成的，以及我是否可以以某种方式查看它写入所有这些日志文件的内容。（评论中有人告诉我这是 MS Access 格式的事务日志文件，用于 DHCP 服务数据库） 更新Windows Server 2012 DHCP 服务器的疯狂行为没有再出现。这似乎是一次意外。
