Wygenerowałem zrzuty na czterech serwerach i analizuję dane wyjściowe! Threadpool i! Threads. Zauważyłem mniej więcej spójne dane wyjściowe:

0:024> !threadpool
CPU utilization 0%
Worker Thread: Total: 2 Running: 0 Idle: 2 MaxLimit: 200 MinLimit: 2
Work Request in Queue: 0
Number of Timers: 27
Completion Port Thread:Total: 2 Free: 0 MaxFree: 4 CurrentLimit: 2 MaxLimit: 200 MinLimit: 2<p></p>

!threads -special
ThreadCount: 32
UnstartedThread: 0
BackgroundThread: 19
PendingThread: 0
DeadThread: 13
Hosted Runtime: no


My questions are:

1)How can I determine what the source of those 27 timers are?

2)What does 13 dead threads mean?

3)One of my threads is marked as having a lock. If i switch to that thread and run !clrstack, i see the following - is it related to my timers?


0:027> !clrstack
