I see a significant amount of java.lang.RuntimeException: De-serialization problem: errors, looks like this

[2024-10-25 00:48:12] TRACE: {Operation ID: 9bb6118b-c431-4485-96b1-51f79076d002} [v1_0_0GetInitCommand] (Command ID: affed89e-51ec-4276-a8cd-57f011014da4) Error message for operation id: 498ee479-7839-4550-8905-27900d13880a, keyword: 0xb8b904c73d2fb4d8c173298a51c27fab70222c320e8bc719d555136ada4201a5f954c021257ca069939dbb5695157dc796f69678 : Received NACK response from node during v1_0_0GetInitCommand.

I have no idea what it is and how it affects node operation. Node is still running. Here is some logs - log_1.txt Please let me know how I can help with it.

Duplicate of #3344

Also seeing lots of these on my nodes.

@Mihajlo-Pavlovic Just to double check here. #3344 is also blazegraph related issue. But the exception is different NoSuchFileException: /root/ot-node/blazegraph.jnl vs De-serialization problem. So despite that the actual failure mechanism is the same, is that correct?

Mihajlo-Pavlovic commented 1 month ago

In both cases cause is blazegraph issue on remote node.

@u-hubar we should add check that node can't start if node has issue with blazegraph.jnl file
