我的多台工作站在下午的时候同时出现了蓝屏，错误代码是：
0x00000019(0x0000000020,0xfffffa802c24b660,0fffffa802c24b880,0x00000004220016)
我检查了日志，没有特别的报错，检查了dump文件，检查的结果如下：
BAD_POOL_HEADER (19)The pool is already corrupt at the time of the current request.This may or may not be due to the caller.The internal pool links must be walked to figure out a possible cause ofthe problem, and then special pool applied to the suspect tags or the driververifier to a suspect driver.Arguments:Arg1: 0000000000000020, a pool block header size is corrupt.Arg2: fffffa80307585c0, The pool entry we were looking for within the page.Arg3: fffffa80307587e0, The next pool entry.Arg4: 000000000422001f, (reserved)
