COM+ problem - components get stucked

Hi,
I have the following problem: from time to time my com+ package just
stops responding. In com+ management console I can see that activation
time of some components is huge and is increasing forever. There are
no exception reported, neither applicative nor system. There are no
database deadlocks as well. More interesting - there are also no
errors about failure on creation of new component. It looks like com+
just stops responding to calls in this situation. After manual
shutdown of com+ package it resumes to work just fine.

The server is written in C# using Enterprise Services, and objects are
disposed and pooled properly. It happens both on W2K and 2003 server
machines.

Question 1 - does anybody experienced something like this?
Question 2 - is there a way to limit the activation time for
components? I can limit a transaction or object creation timeout, but
looks like there is no option for forcefull termination of "stucked"
component.

TIA

Question 1 - does anybody experienced something like this?
Yes; c# Serviced Component running on a W2K box accessing a SQLServer
on a 2003 machine. If Trasactions are set to Required or Requires new
the object instantiates and hangs around until I shut down the
package. No processor usgaes, no db deadlock. The last command
issued to the db is sp_reset_connection (this happens when the
connection is opened). If I run the components on a 2003 box (or the
same box as the db - not sure which) I don't get the problem. If
transactions are turned off (i.e. Supports Transaction) - no problem.

Question 2 - is there a way to limit the activation time for
components?
Don't know!

To fix this issue, at the end of methods call this.dispose().

seeing the same situation in my COM+ / C# Service Components.
but it's only happend about once a week on a heavy loaded system.

I'ts mission critical , appreicate if a way to fix this,
MS should make this combination rock solid and very helpful in trouble
shooting as it's in the enterprise mission critical spectrum...

in the following eventLog, the client is vb6 calling C# serviced
components...

This happens if you don't release components

Look into:
ServicedComponent.Dispose()

Dispose() method

or if in C#, the "using" statement.

Of course I did !! :-)
but it seems I did it in a inperfect way.
1. my client is alwasy vb.
2. I have Log4Net wrapper inside the clean up code, It seems the
un-predicability of finalizing order , will sometimes disable my
Dispose()....

the Using statement seems cool, but I find it not that hany since it has a
"style" to apply in your code... appreciate if someone can have a "how to
apply using in your C# code" courseware...
