I believe this is caused because quartz is not meant for triggering jobs
every few milliseconds etc, so it does not function very well as
high-performance "heart beat" or ticker.
IIRC if quartz job does not finish in time, new job is fired before
previous finished, meaning that you have 50ms continous ticker that gets
hung up in DB call, those calls start piling up.
