------------------------------------------

             Summary: Add support for configuring JCIFS connector's resilience to SMB exceptions before throwing a ServiceInterruption
                 Key: CONNECTORS-1600
                 URL: https://issues.apache.org/jira/browse/CONNECTORS-1600
             Project: ManifoldCF
          Issue Type: Bug
          Components: JCIFS connector
    Affects Versions: ManifoldCF 2.12, ManifoldCF 2.11, ManifoldCF 2.10
            Reporter: Tang Huan Song


This is a improvement request regarding the JCIFS(-ng) connector's exception handling behavior.

After examining the JCIFS connector code, I've found that the number of retries given consecutive identical SMB exceptions and the total number of retries per file/request is hardcoded within the connector at retriesRemaining=3 and totalTries=5 respectively.

Depending on the amount of traffic a file server regularly handles, the probability of any given SMB request failing, and correspondingly the total number of SMB request failures for a given file request will vary. As a result, the current hardcoded values may cause ManifoldCF to abandon the job in the event of high traffic.

I would like to suggest making these values configurable, as a connector-wide setting modified via ManifoldCF's properties.xml or a per-connection setting modified via the corresponding repository connection's page.
