Almost 100% RAM usage and high mspt fluctuation

Long story short, we have a modded (cobblemon + a couple of other mods) fabric server with a minimum of 10 players and a maximum of around 60.
Current specs are Ryzen 9 7950, 16GB of RAM allocated to the server. Current servercore dynamic config:

dynamic:
  # Enables dynamic performance checks.
  enabled: true
  # The average MSPT to target.
  target-mspt: 30
  # The settings that will be decreased when the server is overloaded, in the specified order.
  # You can remove settings from the list that you don't want to be dynamically adjusted.
  # ► max = The maximum value the server will increase the setting to.
  # ► min = The minimum value the server will decrease the setting to.
  # ► increment = The amount the setting will be increased or decreased by.
  # ► interval = The amount of seconds between each check to increase or decrease.
  dynamic-settings:
    - setting: 'CHUNK_TICK_DISTANCE'
      max: 6
      min: 2
      increment: 1
      interval: 15

    - setting: 'SIMULATION_DISTANCE'
      max: 6
      min: 2
      increment: 1
      interval: 15

    - setting: 'VIEW_DISTANCE'
      max: 10
      min: 6
      increment: 1
      interval: 150

    - setting: 'MOBCAP_PERCENTAGE'
      max: 70
      min: 15
      increment: 5
      interval: 15

    - setting: 'VIEW_DISTANCE'
      max: 6
      min: 4
      increment: 1
      interval: 150

Spark report: https://spark.lucko.me/zhcW6IW8eH (the server had been up for 15h at the time of this report, we restart the server daily unless we are hosting an event a that time, then we try to restart it a bit earlier/later)

It's worth noting we recently introduced a custom mod so we dont know if that's causing this behaviour. We are checking it rn.
Also, there is a second server running in the machine (basically a test environment for us), using the same config as the main server (without bluemap tho). Dont think this is an issue since we have plenty of ram available if needed and we should have enough threads for both of them

If anyone could help us or has any theory about this behaviour we would appreciate it
