Server

After making some changes to FTBChunks, pretty much all bases finally unload after the members of the party logging off.

However, 2 bases stay loaded and they affect the server performance. After some digging it seems entity.justdirethings.portal_entity is a chunkloader (according to Crash Utilities). These are portals created by the Portal Gun and Advanced Portal Gun (justdirethings:portal_gun and justdirethings:portal_gun_v2) from the Just Dire Things mod.

Don't see anything about chunk loading settings in the server config file -> (justdirethings-common.toml)
#Portal Guns
[portal_gun]
#The maximum amount of Forge Energy the Portal Gun (V1) can hold in its buffer
#Range: > 1
portal_gun_v1_rf_capacity = 100000
#The Forge Energy cost to fire the Portal Gun (V1) projectile
#Range: > 1
portal_gun_v1_rf_cost = 1000
#The maximum amount of Forge Energy the Portal Gun (V2) can hold in its buffer
#Range: > 1
portal_gun_v2_rf_capacity = 1000000
#The Forge Energy cost to fire the Portal Gun (V2) projectile
#Range: > 1
portal_gun_v2_rf_cost = 5000

If there is no way to disable the chunk loading, the items will need to be put on the banned item list and the recipes removed.
