"Unable to read data from the transport connection" exception

[Muscha]

Hello,

Every now and then my application throw this exception:

"Unable to read data from the transport connection"

And when I break into the Visual Studio, the thread where it failed has none
of my code and the following is the call stack:


system.dll!Syst em.Net.Connecti on.ReadCallback (System.IAsyncR esult
asyncResult = {System.Net.Soc kets.Overlapped AsyncResult}) + 0x37d bytes



system.dll!Syst em.Net.LazyAsyn cResult.InvokeC allback() + 0x27 bytes



system.dll!Syst em.Net.LazyAsyn cResult.InvokeC allback(bool
completedSynchr onously = false, System.Object result = {0}) + 0x23 bytes



system.dll!Syst em.Net.Sockets. OverlappedAsync Result.Completi onPortCallback( u
int errorCode = 10038, uint numBytes = 0, System.Threadin g.NativeOverlap ped*
nativeOverlappe d = 220220032) + 0xf2 bytes



Question is how do I know *where* exactly in my code that cause this
exception? I really don't know what trigger this (apart from from probably
in the Net connection, I do open a number of them and tried to close all
properly). I put all the Net connection in try catch block but none really
shows any problem.

Help, I'm stumped on this one.

thanks,

/m

Re: "Unable to read data from the transport connection&quot ; exception

Update on my previous problem, I found out in my console that I have the
following exception. Hmm seems it is related with something that can't
access a disposed object.

Unhandled Exception: System.IO.IOExc eption: Unable to read data from the
transport connection. ---> System.ObjectDi sposedException : Cannot access a
disposed object.

completedSynchr onously,Object result)
at System.Net.Sock ets.OverlappedA syncResult.Comp letionPortCallb ack(UInt32
errorCode, UInt32 numBytes, NativeOverlappe d* nativeOverlappe d)

Any help will be much appreciated.

thanks,
