This error appears to occur if there are failed "iterations" on one of the slaves.

There appears to be a logic issue in the replications.js code:
{code:title=replication.js}
var getIterations = function(slave) {

    var iterations = [];

    var find = function(list, date) {
        return list.filter(function(e) {return e.date == date});
    };

    for (var i in slave.indexReplicatedAtList) {
        var date = slave.indexReplicatedAtList[i];
        var iteration = {date:date, status:"replicated", latest: false};
        if (date == slave.indexReplicatedAt) {
            iteration.latest = true;
        }
        iterations.push(iteration);
    }

    for (var i in slave.replicationFailedAtList) {
        var failedDate = slave.replicationFailedAtList[i];
        var matchingIterations = find(iterations, failedDate);
        if (matchingIterations) {
            iteration = matchingIterations[0];
        } else {
            iteration = {date: failedDate, latest:false};
            iterations.push(iteration);
        }
        iteration.status = "failed";
        if (failedDate == slave.replicationFailedAt) {
            iteration.latest = true;
        }
    }
    iterations.sort(function(a,b){ return a.date> b.date;}).reverse();
    return iterations;
};
{code}

The `iteration` variable doesn't exist if there are no elements in  `slave.indexReplicatedAtList`.

This error was encountered while still working out firewall issues to allow for replication. We've since removed all solr data and re-installed and the error no longer occurs for us. I no longer see any failed iterations.
