    Thread Queue Blocked for 4294967295 seconds.

      HI all,

       

      Got this question recently from a customer, and I figured I would post this here, because I think it has come up before.    When looking through the logs, you will often see this text (with this exact huge number).

      Thread Queue Blocked for 4294967295 seconds.


      I did a little digging on this and it looks like what this is saying is that a thread is going into a blocked state (waiting for something to happen) and the huge number basically means infinite. There is a possibility of the thread waiting forever for something to happen (like this) or you might also see instances where a thread is going into a blocked state for 300 seconds (for instance) . That just means that if the something that it was waiting for doesn't happen in 300 seconds, it will time out the blocked state and do something.


      I think sometimes people see this in the log and think that something took a very long time to happen, or that there must be a bug because that number is so big, but this is not the case.

          If you are seeing this at startup, it is normal. Ignore it.

           

          I'm sure there is some technical explanation, but I have *always* seen this, and recall there was some explanation from Motorola with advice to ignore. You might search the forum.

           

          If you are seeing it other than at startup, I might be concerned.

           

          I think it should actually be interpreted as "thread queue has been blocked", not "will be blocked". I don't see how it is possible to know how long the thread queue will be blocked. If you could do that, it could make you very, very wealthy.
