Message "Inventory Full" while more than 100 slots over.

[M3NTI0N]

Expected Behavior

Just loot pokestops until the bag is full.

Actual Behavior

Tells me that the bags are full while there are still atleast 100 slots open.

Shows message:
2016-08-07 11:16:17,527 [MoveToFort] [INFO] [inventory_full] Not moving to any forts as there aren't enough space. You might want to change your config to recycle more items if this message appears consistently.

Can you check if it's the same issue as #2942 ?
Probably only config "Pokeball", but no "GreatBall" etc?
