Hi, +-From: matsuda <mats...@i4s.co.jp> ------ |_Date: Thu, 14 Jan 2010 12:16:31 +0900 __ | |I report the following test result. |[summary] | The problem doesn't seem to depend on HardWare or Network. ...
Thank you for detailed test results. Ok, so I'll try to reproduce that problem on our environment. |I'm not sure how to get the thread dump. |This problem doesn't make Exception. |It is only kept with Channel#isClose() is true. |Do you suggest what should I correct? I have some questions. * During runnging your test program, 100 sshd will run on the remote host. For example, # ps ax|grep sshd | grep notty|wc 100 600 4500 How many sshd will run at the problem happning? * Is the result of "ls -la" huge? * Is there some changes if in is read? I mean that, ... Channel channel = null; channel=thisSession.openChannel("exec"); ((ChannelExec)channel).setCommand( "ls -la" ); ( (ChannelExec)channel ).setPty( true ); // ByteArrayOutputStream baos = new ByteArrayOutputStream(); // channel.setOutputStream( baos ); InputStream in=channel.getInputStream(); long start = System.currentTimeMillis(); channel.connect(); byte[] tmp=new byte[1024]; while(true){ long end = System.currentTimeMillis(); if(in.available()>0){ int i = in.read(tmp, 0, tmp.length); } ...
