Question

I have a multithreaded C# application where each thread has it’s own set of db connections. Each thread uses TransactionScope / DTC. Sometimes, I get a “The transaction has aborted” exception. It’s not from a timeout since it occurs in less than 2 seconds from starting the transaction.

Here’s the stacktrace:

at
System.Transactions.TransactionStateAborted.BeginCommit(InternalTransaction
tx, Boolean asyncCommit, AsyncCallback
asyncCallback, Object asyncState) at
System.Transactions.CommittableTransaction.Commit()
at
System.Transactions.TransactionScope.InternalDispose()
at
System.Transactions.TransactionScope.Dispose()
at MyNamespace.CallingMethod()

It happenes very infrequently, say once in 100,000 transactions.

Environment:
Windows Server 2003
.Net 2.0
Connects to SqlServer 2005

Any ideas on why this is occuring?
Thanks!

I think this is attributed to network instability. It is very infrequent, and hasn’t reared it’s ugly head in quite a few months now.
