Canon EDI logs show the same user attempting to login every 5 minutes

Symptoms

Viewing EDI logs show the same user attempting to login every 5 minutes.

Viewing the on-device debugging logs shows the transaction reaper start then interrupted by an automatic logout.

Viewing the on-device transaction logs shows transactions in the log.

Cause
A too frequent auto clear timer setting on a Canon MFP can interfere with the off-line transaction reaper thread causing it to exit prematurely.  This happens before the retry count is incremented so the retry count is always 1.

How to reproduce:

1. Set the auto clear timer on the Canon MFP to 20 seconds. (this is for illustration only, other values may also cause the issue

2. Login

3. Start a copy job

4. Unplug the network cable

5. Let the job complete.

6. Wait 15 seconds or so

7. Plug the network cable in

8. Logout

9. Wait about 5 minutes

10. View the on-device logs and note when the transaction reaper runs and if it completes.

11. View the on-device transaction cache and determine if off-line transactions still exist

12. View the EDI logs and not if the user is attempted to login at 5 minute interval

13. Repeat 9-12  three more times to ensure the transaction reaper ran at least 15 minutes

14. If transactions remain, the issue is exhibiting.

Note that in step 4, any error could cause the job to fail to commit to Pharos.  Edi server is down, etc.
