If your batch is stuck at "Process" status and not completing then please check the error logs. If there is an error log with description -"batchEntryChargeProcessor already running" then that means 2 batch processors are submitted.

The reason behind this could be:

Batch 1 - submitted (note, batch processors may take up to an hour to actually start - depending on Salesforce servers)

Batch 2 - submitted (the 1st one might not have started - hence error).

Solution:

Please make sure you submit the batch once.

For submitting the same Batch Again

1. First check the Payment Txn associated are completed, if not

2. Change status to Open Save

3. Process it again

Please do not make changes after the batch has been submitted.
