synchronizeReplica - failed to synchronize

[ColinCole]

Hi,

I've been encountering a recurring issue when trying to sync my non-spatial related tables. After following the requests through Fiddler, it looks like the sync process [AGSGDBSyncTask syncGeodatabase] is hanging on the REST -synchronizeReplica method and then fails. But as usual, there are no helpful error messages in the XCode debugger. Has anyone else ran into a problem similar to this? The error message I get is below:

Error Domain=NSCocoaErrorDomain Code=500 "The operation couldn’t be completed. Failed to synchronize." UserInfo=0x1ab2b4d0 {NSURL=http://gisdemo1.cdmsmith.com/arcgis/rest/services/Mansfield_MA_FS/FeatureServer/jobs/j578830f8108744..., responseJSON={

    error =     {

        code = 500;

        description = "Failed to synchronize.";

    };

    lastUpdatedTime = 1421440085000;

    replicaName = "Ags_Fs_1421439987693";

    resultUrl = "";

    status = Failed;

    submissionTime = 1421440081000;

}, NSLocalizedFailureReason=Failed to synchronize.}

Note: I can download / sync my spatial feature class with no problems.

Thanks for any help,

Colin
