ssh_exchange_identification: Connection closed by remote host

[marafa]

i have a setup with about 30 Suse Linux Enterpise Server 10 Service Pack 1 and i have a backup script that in pseudo code looks like:

for server in 1 to 30
do
ssh $server tar -cz $logdir && scp $logdir.tar.gz $central_log_repo &
done

the problem is while all the servers get the logs tarred, the return trip doesnt allows work. random servers log this error:
ssh_exchange_identification: Connection closed by remote host
where of course remote host is the $central_log_repo
there is no mention on $central_log_repo of any attempt by the offending server(s)


in summary, on one run server5 could scp the tarfile to $central_log_repo and on another it might fail because of the ssh error. how do i fix this?
