[cross-project-issues-dev] Hudson: ssh channel is closed error

[webmaster <webmaster@xxxxxxxxxxx>]

 Folks,

As you may know, there is currently an SSH problem with Hudson.  On 
occasion, the SSH channel between a master and a slave will end, and 
your jobs will get an error as posted below.

We've tried upgrading to a later version of Hudson, and we had much 
bigger problems, so we have reverted.

If you encounter this SSH error, please send webmaster an email directly 
to avoid flooding this list.

I've kicked slave1 just now.

Thanks,

Denis
