    Description

      During acceptance testing for KIT, they tried OSS failover while running several applications. And applications got IO errors (can't create file and similar messages). This should not happen and IO should just stall till failover happens.
      The clients were running 2.4 and servers were 2.1.5. We tried with 2.1.5 clients and did not see this issue. I have attached the client and server logs.
