I've been hosting it for about 2 years, running in a container on a Proxmox host (a DL380G7 with 128GB RAM and a DS4243 JBOD in a tailor-made enclosure under the stairs here at the farm) together with a bunch of other services. It is not used all that often but when I need it it is there and works as intended. After configuring it I have not had to do anything else than run apt update && apt dist-upgrade every now and then. It is a bit of a memory hog just like most other jvm-based services but it is reliable and dependable.
