Alcurex having trouble with the NSR wallet

Continuing the discussion from Wall Observer - NuShares price movement tracking & discussion:

Alcurex is having trouble with their wallet. @sigmike

In chat they mentioned something about:

not work with RPC API.

NSR wallet basically works, but witdraw via RPC call will often give error code -4 and no send.

error log: SendMoney() : Error: Transaction creation failed

manually its sending, but will take like 5 minutes.

This is a better description of the problem they are having.

it sounds like they’ve minted with their wallet and now have a ton of transaction inputs. perhaps they could stop minting and combine all of the inputs into few big outputs.

Thank you @lissajous for providing the needed details. @jooize sent me the same details in a PM and I provided some information he sent them. Hopefully this will solve their problem. Here’s my answer for the record:

Unfortunately this error has never been very verbose, even in the log so [providing the complete log] won’t provide useful information.

Are they sending large amounts of NSR? One possibility is the transaction is too big. The fact it’s somewhat random and that sending takes a very long time when it works suggests that it may be what’s happening. Do they disable share splitting (splitshareoutputs=0)? That would reduce the transaction size significantly.

If that doesn’t help they may try sending smaller amounts. Or they could first send the shares to themselves after splitting has been disabled, that would merge all the split outputs they received.

There are other possible reasons for this error to appear, but they seem unlikely. To be certain we would have to make a more verbose client.

We could also modify the client so that it reduces splitting when the transaction won’t fit in the maximum size. But all exchanges should really disable splitting.

it sounds like they’ve minted with their wallet and now have a ton of transaction inputs. perhaps they could stop minting and combine all of the inputs into few big outputs.

Even if they did not mint they certainly received split outputs from their users. Disabling their own splitting will reduce transaction size by about half if they don’t already, and will also prevent further splitting while they mint.

Disabling minting would be a good to reduce CPU usage and to prevent shares from being locked. But it’s not possible right now without altering the source code. I added an option to disable minting already but it hasn’t been released.
