Tang Huan Song commented on CONNECTORS-1600:
--------------------------------------------
Setting retriesRemaining=5 and totalTries=8Â enabled the job to complete in a
reliable fashion. It is likely that the heavy traffic subsided in the
additional retries, allowing for the requests to succeed.
However, I acknowledge that luck played a part in the job's successes, and I am
of the opinion that changing the value doesn't alleviate the high-traffic
issue, but merely works around it. Though it would be beneficial to us were the
retry counts made configurable, I have no objections if you choose not to
implement this.
Thanks for your thoughts!

> Key: CONNECTORS-1600
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1600
> Project: ManifoldCF
> Issue Type: Improvement
> Components: JCIFS connector
> Affects Versions: ManifoldCF 2.10, ManifoldCF 2.11, ManifoldCF 2.12
> Reporter: Tang Huan Song
> Priority: Major
>
> 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.
