Bill: Can you please set your system clock correctly? It is very
disconcerting to see emails in my box dated a month in the future.

Synopsis
-------- I am running ant 6.1.2 on XP Pro and have a test
case that produces SSH connection failures by repetitively
running the same <sshexec .../> task.
The first failure occurs after about two thirds (10) of the tasks
have executed. At this point ant hangs up for about 2 minutes,
then logs the following exception on the console.
com.jcraft.jsch.JSchException: Session.connect: java.io.IOException: .
If I then run the build again it hangs up immediately for 20 seconds,
then logs the following exception on the console.
com.jcraft.jsch.JSchException: Session.connect:
java.net.ConnectException: Connection timed out: connect
Once the failure occurs I must wait about ten minutes until
the connection timeouts go away and I can run the build
again until the connection problem reappears.
The server is running Openssh on fedora RC2.
Question 1
----------
Is this a known problem with SSHExec (ant), jsch, or openssh?

The build file is very simple, and looks like this:

Running the build produces the following console output:

console output from
[sshexec] Connecting to xxx.com:22 tasks disappear
at this point?
[sshexec] Connecting to xxx.com:22
