Hello! When a client node joins or leaves, it will cause a Partition Map Exchange which includes a brief pause.
If you have requests with very short timeouts, you can see that some operations will fail. I think there are some client node PME optimizations in the works, in the meantime consider increasing timeouts or avoiding clients' joins/leaves during operation.
