In the function xs_tcp_read_callback, when the rpc_rqst are unable to be obtained, the connection will be closed and the system will give a KERN_WARNING "Callback slot table overflowed". We know that although there is only one rpc_rqst is prealloced, metadata server cannot send two or more callback requests to one client at the same time, because there is only one slot on the metadate server for the client. Now, in my test, the KERN_WARNING "Callback slot table overflowed" always occurs. So, I want to know that what caused the rpc_rqst unable to be obtained. Maybe there are retransmissions in the systems. Are there anybody can expain the reason for us? -- 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
