Explain "Channel flush failed" error

In RFA configuration for RSSL consumer connections, we set the parameter "serverList" with the following ADSs:
"server74", "server75", "server76", "server09", "server10".

During an recovery training, the 3 first ADSs have been separated from the network so that they can not be reached by our RFA clients.
During our training RFA failed to connect to the 4th ADSs and we got the following error:

Error: RSSL Channel flush failed on connection "Default::Connection_Sub server76:14002".  Channel will be closed.  (Internal debug info: "<..\..\..\Rssl\Impl\rsslImpl.c:1692> rsslFlush() Error: 0007 Only Channels in RSSL_CH_STATE_ACTIVE state can flush.", errno: 0)


Can you give us more details about this error ?

We're using RFA C++ 7.6.2.L1.

Thanks.

The error means that RFA failed to flush data to RSSL connection, because the connection is not in active state. The connection might not be successfully established or might be somehow closed. It will be helpful, if you can provide the full rfa.log file.

Could you also try configure only "server09" in the server list? Does the issue always occur with this ADS?

Yes in our next global test, we'll set up different configurations with the ADS in a different order.

Thanks for your answer.

Regards.
