redis-server crashes when it can't connect to MASTER and client connects to SLAVE

[GoogleCodeExporter]

I have setup a redis SLAVE to replicate from a MASTER, and I noticed if the 
MASTER goes down, 
the SLAVE can't accept anymore connections because it crashes after it receives 
a command.

I am using Redis version 1.02

Here is what I did:

MASTER: ./redis-server redis.conf
SLAVE: ./redis-server redis.conf
SLAVE: ./redis-cli info
... output as expected
MASTER: ./redis-cli shutdown
SLAVE: ./redis-cli info
... OOPS

Here is the logfile output:

low condition memory. To fix this issue add 'vm.
overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 
'sysctl 
vm.overcommit_memory=1' for this to take effect.

No problem it's a very simple issue :) Actually it dies *only* with INFO 
command. All the 
rest is working.
