Sync problem in mainnet

Tech Support
#1

My dual node’s(http://symbol.yamode.jp:3000) synchronization is stopping now by something error.
what is causing and what can I do for solving this problem?

The error codes is below.

I’m using Symbol-bootstrap(v1.0.2), and healthCheck is good at all. node/health is displaying ‘up’ both nodeApi and db.
I did reboot symbol-bootstrap, and Ubuntu OS, but ineffective.

Hi yamnode,

Have you found a solution to this issue?

My node started acting strange today, somehow the balance reported from my node was not in align with peers so I have tried symbol-bootstrap resetData and started encountering the similar issue

I’m not quite sure what to do now…

Actually I’ve found out why… For me it was due to modifying the harvestBeneficiaryPercentage: 25. I thought it might be helpful to reduce it down but that caused all the shits to happen ( non stop harvesting, and unable to sync ). After removing this customization, symbol-bootstrap stop; symbol-bootstrap resetData; symbol-bootstrap start; fixed the issue for me.

It’s network properties. You can change to 0 or to 25. Nothing else.

Thanks for info. The documentation isn’t stating that available options are 0, 25

harvestBeneficiaryPercentage

harvestBeneficiaryPercentage uint8_t 10 25
Percentage of the harvested fee that is collected by the beneficiary account.

I’ve tried reducing to 10 to match with a value in the testnet and somehow my node started harvesting non-stop and corrupted the database so I think there should be some warning in the documentation too. I will find some time to reproduce and open a case for improved documentation.

It’s network properties. You can’t change it whatever you want. It will cause your node fork from network:

Ah got it. I’m new to running a node so, Thanks for teaching!
