Internally, the BlackBerry Enterprise Server assigns threads to handle specific operations, for example, sending a message to a BlackBerry wireless device, or synchronizing wirelessly a delete action on the device. Occasionally, these threads can take an excessive amount of time to complete their work. In this scenario where some tasks do not complete and the assigned thread becomes unresponsive, this is the "hung thread".

See RIM KB - KB-03124

nice one thanks.

I'd searched the RIM KB, but not found anything!

[bbgirl]

awesome. only, thing is if we could figure which threads are for which actions...

that would be awesome.

A thread can perform a number of operations; it is not assigned to perform a specific set of tasks on the BES.

[Rich Y]

is anyone aware of how we can monitor hung threads without running some monitoring software such as BoxTone or NetIQ?

I'd start with the resource kit. Search the user guide for "thread" for info on what's in there. Whether it'll be useful to you will probably depend on what BES version you're on.

Very basic way to search for Hung Thread.

Open the Magt debug log...Do a search for waitcount=

Depending on how large your BES environment is you may see several threads which have a waitcount. What you should not see is the waitcount steadily increasing...waitcount = 5 etc....If you see a waitcount greater than 5 it should be considered a hung thread.

So now your next question would be...what do I do in the event of a hung thread? I am told the only recourse is to restart the server...does anyone know differently?

According to our RIM technical contact, all you can do is restart the BES/MAGT OR wait for the thread to clear. While its useful to know when they are happening, I think the real trick is to find the cause.

Someone told me that Boxtone can give you the cause and some trending data around hung threads (which user causes them and which mail server they are coming from). Can anyone confirm this?

[dropscience]

How about an enterprise activation that takes forever? would that be classified as a hung thread?
