We do use NR and have also experienced performance degradation over time, but I 
had not gotten to the bottom of it yet. Thank you so much for this lead. Is 
there a public link to the ticket?

    Hi.

    We use newrelic to gather stats via their solr-jmx instrumentation
    implementation. I've noticed a memory leak with their implementation that
    allows metrics to be registered, but not deregistered (as MetricsManager
    does in Solr)

    I was wondering if anyone else uses newrelic and has noticed performance
    degradation over time in particular running out of heap as the old gen gets
    filled up and exhausted.

    I've submitted a ticket to newrelic  on this issue

    Kind regards,
    Dan
