No limit on collectd memory cache

Description

Running TrueNAS-12.0-U8.1 with a remote graphite server configured. It's been working for a long time but I recently brought the graphite server down for an extended time.

While the graphite server has been down I've noticed the "Services" memory consumption of TrueNAS kept increasing and increasing. I confirmed with htop that it's collectd using more and more memory.

Collectd was up to 70% of system memory when I brought the graphite server online. Immediately after I brought graphite back online collectd started flushing it's cache. I watched it slowly flush all the way back down to ~1.5%.

I'm assuming an in memory cache is expected behavior but there should be a more sane limit to its size. It was up to 70% of my system's 32GB. I don't know if it would have caused problems when it got to 100% or if a limit would have kicked in.

Apologies if a high impact is inappropriate here but this felt like a memory leak to me.
