Ok,
now I have problem with low ABN again even if my abnweight is more than 256k.
Now I found this in log:

So unfortunately this didn't lead to any new revelations (to improve ABN) yet.
Although this looks strange: ABN Tx Total Bal 1922976.605973, Needed 1926795.382894,
This means the wallet itself, when counting confirmed transactions (coinbases that are confirmed, and all tx's to yourself deeper than 6 confirms) calculates a balance of 1.9229MM, while the ABN coin selector seeks coins of depth 5+ that it would need 1.9267MM to make 256k weight, meaning there is one coin in your wallet (about 4K, probably a reward) that is not quite old enough to be used by ABN.
So by now the miner is probably mining again. Ill try to improve this message.
EDIT: Btw Orbis you can type 'exec getabnweight 256000 1' to see the details of the coins selected to arrive @ 256k.
