I guess the ssh guys forgot to make an ssync like scp for rcp and ssh for rsh. I have found ssh tunnels a bit troublesome in some cases, yet solid in others. Running out of memory may be shortage of swap for VM, as almost nobody uses RAM directly any more.
I make my mirrors with: find * -newer mark_file -type f|cpio make archive|some compressor|ssh or rsh "matching uncompressor|cpio unpack update only make dirs". It spreads the load out and gives me choice of compressors to match network/CPU speed. I can even split the load up with "find ...|xdemux n '...' ", my dumb mux tool, into N parallel streams. I can add nice to the compressors if there are residents that might need CPU on the sending end. Just create a new mark file and sleep 1 second before starting each run, and when done, make the new mark the next old mark file.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
NAME
ssh-keysign -- ssh helper program for hostbased authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
HostbasedAuthentication to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
authentication is used.
