The reason payouts get stuck is because the dev of this coin has not released any updated to fix the wallet "stuck" issue like coins such at BCN and MRO have done.
On the pools, when the daemon auto saves, the wallet times out and then gets "stuck," causing payouts to get stuck until the wallet is resynced.
This is a known issue, and was a known issue with other coins as well, and the dev's for those other coins have fixed this issue.
I have notified the dev for Aeon of this issue as well as the fix, publicly on this thread, but I have yet to see an update to fix it. Hopefully there is was soon. For now, like I stated a few posts up, I just got back to my computer and I will go through and fix all pending payments shortly, should go out within the next hour.
Please check current Monero master tree if the "fix" is there. I'd say it isn't simply because previous trivial retry could lead to more trouble like incorrect wallet status which may be even more difficult for pools. With current design when aeond is busy wallet won't be able to communicate with it and will be "stuck". So it has to be restarted. But it affects only pools using pre-baked and very stupid p2p code. For miners and coin owners it's no big deal. Pool owners should invest time and effort to come up with reliable pool software I'd say.
Bytecoin implemented some more improvements but we all know what happened and how it affected coin price. So rather that be in a hurry because pools are broken we decided to fix code properly and align with the branches we're following. If you think you're fine with previous Monero fix implement it but don't come here then if you need to pay more than what was mined on your pool.
We know about issues like chain loading into memory, transaction splitting and stuck wallet. But all this needs a proper and tested solution not just a quick patch to make it look good. Community is welcome to help, fork aeon and submit patches. It's community coin after all. There is no fully paid developer working 24/7 on the code (not even a paid one). If you take a look into other coin you will see how much problem are still there. Stuck payment is important for miners of course but is really not caused by coin itself, rather by a combination of poor pool sw and old coin design of all Cryptonote currencies.
I'll keep you updated on what's in a pipeline, but stop constantly blaming dev for being responsible for all bad. If you are developer submit fixes, if you are pool owner check whether it's really coin code causing payment issues. Releasing an update for multiple systems and without testnet is challenging and so far we're doing good. Support AEON. Be part of it.
