> 244550997187166214-server1-b.myhost:8983_solr-n_0000000094
> I don't even know what this _MetricsHistoryHandler_ does, but at least
> there's a warning.
> Looking at the code you can see that it has to fail if the hostname of the
> node contains a hyphen:

> {code}
> String[] ids = oid.split("-");
> if (ids.length != 3) { // unknown format
> log.warn("Unknown format of leader id, skipping: " + oid);
> return null;
