I'm not sure what you are asking. Are you saying that the sender channel went into an indoubt state and stayed that way? If that is the case, it is likely that the sender and receiver channels can't agree on the current sequence number. What you'll need to do is determine how many messages actually made it across to the receiving side, and then compare the SEQNUM attribute of both the sender and receiver channels. Once you figure out which one is in error, go ahead and set this attribute to the correct value and the channels should start running again.

If the Sender channel really is in-doubt, then there is a table in the Intercommunication Guide that details the actions you must take to ensure that you either commit or backout the inflight messages correctly.
Failure to follow these guidelines can lead to either lost messages, or duplicate messages.
Cheers,

Check wether both your LSTLUWID's are the same. If not : resolve with backout, if true: resolve with commit...

If you reduce the batchsize on your channel there will be more frequent commits of messages by the channels and it will reduce the window of opportunity for a batch to be in-doubt. Also, even if you did hit that window, the number of messages in-doubt would be less. The tradeoff could be reduced performance if you set the batchsize too small.
