--------------------------------
hi [#Mark Payne],here is my script text:
{code:java}
//
import os
userCountFile = "D:\\99_TestCase\\3_StuckTest\\B5_ALL_CELL_USER_COUNT_"
try:
flowFile = session.get()
if (flowFile != None):
filename = flowFile.getAttribute('filename')
userCountName = userCountFile + filename[12:]
#flowFile = session.putAttribute(flowFile, 'userCountName',
userCountName)
if os.path.exists(userCountName):
session.transfer(flowFile, REL_SUCCESS)
else:
session.transfer(flowFile, REL_FAILURE)
else:
pass
except Exception as e:
log.error('Error!')
else:
pass
finally:
pass
{code}
I'm sure that the flowFile is in the path, so it normally remove by
StandardProcessSeesion::unacknowledgedFlowFiles();but in this situation, I
found but not sure that the unacknowledgedFlowFiles in
StandardProcessSeesion::acknowledgeRecords() was empty,or recordMap never be
puted in StandardProcessSeesion::commit().

> The following segment of workflow demonstrates the issue. The queue reports
> that there are items within it, but they cannot be listed, even after
> stopping the consumer (and producer). Since this is in a Docker Container, it
> is unlikely an OS error.

> I do not currently have a simplified example workflow to recreate the error,
> but can work on it.
