System.Transactions.TransactionAbortedException with no reason

Question

Occasionally I am receiving the following error:
System.Transactions.TransactionAbortedException: The transaction has aborted. ---> System.InvalidOperationException: The requested operation cannot be completed because the connection
has been broken.
The exception is happening on the Dispose method of
TransactionScope although nothing special happened, no timeout occur and the SQL server
is OK.
This method is executed every 10 minutes and the problem occurs occasionally, nothing seems to be difference when the problem does not occur.
The stack trace is:
--- End of inner exception stack trace ---
at System.Transactions.TransactionStateAborted.EndCommit(InternalTransaction tx)
at System.Transactions.CommittableTransaction.Commit()
at System.Transactions.TransactionScope.InternalDispose()
at System.Transactions.TransactionScope.Dispose()
I am having the following code:
using (TransactionScope
ts = new
TransactionScope(TransactionScopeOption.Required,
new
TimeSpan(0, 0, 30)))
using (m_SQLConnection =
new
SqlConnection(m_SQLConnectionstring))
m_SQLConnection.Open();
SQLCommand.Connection = m_SQLConnection;
SQLCommand.CommandTimeout = 1;
for (int i=0; i <2; i++)
SQLCommand.ExecuteNonQuery();
ts.Complete();
As I said timeout does not occur since all those commands takes about 10 ms to execute,
the command timeout is 1 second and the transaction timeout is 30 seconds.
