Invalid Reference Block Transaction's reference block did not match

[guaiguaihw]

We start a program to sync our accounts' transactions, but meet some errors from the noodes.
It seems that the transacations did not belong to the main network, but It should not happen because our transactions are always send to the main network.
I wonder in what circumstances that would happend??? The details of errors are below:

What action that you did to produce the above error messages? Normally the above error message appears when you are referring a block at a fork.

[guaiguaihw]

The actions are transfer. @andriantolie

[andriantolie]

Are you sending the transaction to the same node where you get your reference block from?
(If you are using cleos, it should be the same node. I'm not sure what the program you mentioned above is actually doing)

[guaiguaihw]

@andriantolie We use A node to send transaction, use B node to get actions. Each node are connected to main network. We use http api to get and send transaction, not cleos. Is It possible that we don't use the same node that cause the error? But two nodes all sync the main network, It can not fork orther chain.

[andriantolie]

Are both nodes head block on par? Or if they differ, how large is the gap?

Which block did you use as reference block? Try to use the lowest last irreversible block between two nodes as the reference block to ensure that the ref block exists in both nodes. And also, you can't refer to a block older than MAX(uint16_t) from head block since ref_block_num is an uint16_t type

[guaiguaihw]

ok, we will pay more attention to what you have mentioned, thanks a lot @andriantolie

[csquan]

same problem,how to resolve?

[csquan]

I have seen log
“maybe_switch_forks ] switching forks from ...” ,then error log"Transaction's reference block did not match. Is this transaction from a different fork?" show,what happened?

[csquan]

why fork?none got this?

[taokayan]

Soft fork is a normal situation on EOS blockchain. If you still have the problem and wish to discuss further, please post it in https://eosio.stackexchange.com.
