hello all,the following is what i encountered when running lotus domino 5 on rhl 2.4.0: after the number of the tcp connections established between the domino server and clients reaches up to 4 or 5 hundred,there always comes port listening failor saying too many files have been opened and clients cannot connect to server any longer as if the listening port(25) dose not work any more(the server process on the server machine will fork a new server process to handle the client request after receiving a request). i cannot figure out,can you give me a hand?any suggestion will be appretiated. thank you. xiong zhao _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
