      Description

      Hello everyone,

      I've been hunting the recent handle corruption issue and I did a small bat file with the following code:

      :loop
      dir C:\
      goto loop

      After creating bat file on a desktop and executing it three times I noticed that the process locks and I am unable to kill it.

      If I break in debugger I see the following stack trace (I am on revision 72609):

      It seems like the process is a zombie because I can see that it prints a message SystemProcessInformation:

      SpiCurrent = (PSYSTEM_PROCESS_INFORMATION) Current;
       
                  if ((Process->ProcessExiting) &&
                      (Process->Pcb.Header.SignalState) &&
                      !(Process->ActiveThreads) &&
                      (IsListEmpty(&Process->Pcb.ThreadListHead)))
                  {
                      DPRINT1("Process %p (%s:%p) is a zombie\n",
                              Process, Process->ImageFileName, Process->UniqueProcessId);
                      CurrentSize = 0;
                      ImageNameMaximumLength = 0;
                      goto Skip;
                  }

      If I simplify my scenario and do not kill the cmd.exe I can see that the processes are stuck in file system handler:
