I assume that / has more data than /var, correct?

Is there perchance a firewall or some other filtering in between the 2
servers.  It sounds like the control connection is getting terminated
since there is no data passing on it.  This can happen with large
volumes when data is being transferred on the data ports and nothing on
the control port.

If you set the NSR_KEEPALIVE_WAIT environment variable in the start up
script on the client to something like 30, this will send a keep alive
packet on the control port every 30 seconds.

You might also try running a backup of / manually on the client with
"-vvv" and/or "-D9" arguments to `save` to get some better output if the
NSR_KEEPALIVE_WAIT doesn't work.  Usually with "-D9" you can see exactly
what's going on.

Happy Hacking!
