Unexplained memory leak? Free RAM goes down over time
Hi LowEndHelpDesk, 
I have a VPS with 2GB of memory. I don't use it a lot, leaving it mostly idle except the IPv6 BGP session (over 6in4) I have with he.net and NetAssist. I don't load the routing table; I just route everything to he.net.
However, I noticed that the memory usage increases slowly over time. I need to hard-reset the VPS every few weeks to restore it. This behaviour started roughly since 2020 started but I haven't made any significant changes to the configuration
Thanks to this beautiful graph from hetrixtools hopefully it explains better:
Memory usage is quite high:
[me@lax2 ~]$ free -h
total used free shared buff/cache available
Mem: 2.1Gi 1.6Gi 95Mi 1.0Mi 366Mi 289Mi
Swap: 303Mi 20Mi 283Mi
You can see that there's actually no application actively consuming memory:

Any ideas?

Looks like it's all being eaten by Slab? Which iirc is kernel-related cache. Try
slabtopand maybe that can give you some hints, or you can share the output here for someone much smarter than myself to help with. lol🦍🍌
Thanks for the pointers! I never realised slab is a thing. Here's the output from slabtop and I will continue Googling tomorrow:
