All matching queues are full.

I have this in Shareaza settings:
min transfers 2
max transfers 2
max in queue 64
In transfer view for this slot i always get 2/4
& then in network view
Refusing upload of "*" to *.*.*.* (*), All matching queues are full.
I don't seem to be able to build up a queue higher than 4 anymore,
I'm sure i share popular, i've used shareaza for eons.
SOS 
btw: I use 2.4.0.0 &can't update yet but plan to upgrade to 2.5.0.0 in near future.
