[zhangtiantian222]

Please answer these questions before submitting your issue. Thanks!
The node runs for a few days, a synchronization exception occurs, and the node is restarted to resume synchronization.

@zhangbinbin625 Please confirm whether your node failed to sync or not? From the attached log, we can't see the exception.
Using this command please: "tail -f logs/tron.log -i pushblock", and watch the output. If the block doesn't change for more than 1 minute, there must be something wrong. Then please provide the detail tron.log.

[zhangtiantian222]

Appear every few days，The tron.log log is all link nodes and is stuck here.

[thinhtn-ibl]

I meet this issue every 2-3 days, the same tron.log as above (java-tron version v3.5.1)

[thinhtn-ibl]

tron.log
I usually meet above issue, restart "FullNode.jar" did not work. Please see my "tron.log"

[thinhtn-ibl]

In the "tron.log" above, I see exception, could anyone explain me about that? Maybe it's reason to disconnect peers for a long time:

@zhangbinbin625 @thinhtn-ibl
hi, the transaction in the block processed with different resultCode，as you mentioned the code is OUT_OF_TIME ，is caused by the low computer performance.
You can increase the maxTimeRatio field in the config, the default is 5.0, so you can try it with 15.0 or 20.0. I think this will make the problem solved.

[thinhtn-ibl]

@shydesky Thanks for your support. I will try and get back to you.

[thinhtn-ibl]

@shydesky Works like a charm! thank you so much!
