Hi, With autoclose trying to close the connection, after the idle timeout in NFSv3 mounts, a bad NFS server may not send the final FIN, leading the client stay in FIN_WAIT_2 state forever. This is easily reproducible by simulating the bad server behavior. I used 'netstat -an | grep 2049' to observer socket state. This is will also stall the other RPC requests from connecting and proceeding as XPRT_CLOSING flag is already set. This can be observed in the 4.14-rc1 as well. This behavior is introduced with the following commit - caf4ccd SUNRPC: Make xs_tcp_close() do a socket shutdown rather than a sock_release Once we reverse this commit, the FIN_WAIT_2 state lasts only for 60 seconds. Any thoughts correcting this behavior? or is this behavior expected? -Thanks, Manjunath -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
