It consists of 10 units of A cluster by Linux(For making you understand well, this will be called Node1 to Node10 here for you.)
The storing the data uses the B function at Node2 always. Therefore, the execution of B function either Master or Slave for node2. When running with B function, we never operate make Node2 as a master.

But running B function on the state of Slave on Node2 occurs the following error towards Node9 someday.

-Error

The error occurs sometimes however it is not reproducible so that the investigation is troublesome. Is there any possible cause for this problem? I mind that it was because of the anti-pattern occurrences for Linux I suppose.

The thing is, when running B function by Node2, the above error occurs towards Node1 as a master, then soon after, all the nodes might be returning to the state of the Node1. Do you think my understanding makes sense?

If using B function at A cluster is not recommended, I am happy to teach whether.
