可以参考下文:\r\n\r\nrsh/rcp maybe using \"reserved\" ports (ie < 1024), of\r\nwhich there are only ~400 available inherently and blocking new\r\nrsh/rcp sessions from being established or due to many connections\r\nin TIME_WAIT status (i.e. wait after close for remote shutdown\r\nretransmission.\r\n\r\nSuggest to increase the existing file descriptors to 8192 and decrease\r\nthe tcp_time_wait_interval from the default of 4 minutes to 1 minute\r\nfor sockets.\r\n\r\nExample:\r\n\r\n# ndd -set /dev/tcp tcp_time_wait_interval 60000

谢了。\r\n最后没有找到好办法，因影响到另外一套系统的正常运行（通过rcp取数据），最后通过重启系统解决问题。\r\n问题时执行# netstat -an |grep \"TIME_WAIT\" | wc -l 的结果\r\n    3554\r\n   \r\n现在系统正常情况下\r\n# netstat -an |grep \"TIME_WAIT\" | wc -l\r\n    2770
