我的线程经常死掉，用了临界区好想不起作用，请高手指点，急！！！（高分求救） (200分)

执行时数据线程经常死掉，不知道为什么，我的临界区使用有问题吗？
以上是部分代码，不知道诸位能否看明白

你的 CS 在什么地方创建的？
另，TaskTimerProc 的内容呢？
贴出来看看才行

procedure TCheckMgr.CheckProc();
var
i:integer;
begin
EnterCriticalSection(CS);
for i:= low(FCheckList) to high(FCheckList)do
FCheckList.CheckKernel;
LeaveCriticalSection(CS);
end;

procedure TCheckMgr.DataProc();
var
i:integer;
begin
EnterCriticalSection(CS);
for i:= low(FCheckList) to high(FCheckList)do
FCheckList.DataKernel;
LeaveCriticalSection(CS);
end;
