NMC: Error -4: Transaction creation failed

[Kumala]

Recently the transaction errors when sending NMC or I0C are increasing, whenever sending larger amounts (sometime a couple of hundreds only), the error:

error: {"code":-4,"message":"Error: Transaction creation failed  "}

shows up. I then have to break down the transaciton into several smaller transactions.

This is normal and occurs when a large number of inputs are used to create the transaction, exceeding the allowed size limit. It's the bane of exchanges that often get lots of small deposits and large withdrawals. I regularly have to compact my wallet by consolidating addresses. It's an issue with pools too where the reward per block is small and people wait until large amounts accrue before withdrawing.

Thus as an Exchange operator I have only one possibility, regularly move all coins out and back in, thus combining the small transactions into larger transactions.

Yes. I keep most funds in a cold wallet so regularly send the hot wallet back to the cold wallet, and retop up the hot wallet from the cold wallet so it's compact.

Ah nice to know how you workaround this issue. I have seen this during testing of ppcoin as well.
