Cisco IP SLA stopped Polling

Hello Experts,
 
I have configured the following ip sla:
 
ip sla 7
icmp-echo 195.1xxx.xxx.xxx
tag sla7_DLR_Package6_DMVPN_195.xxx.xxx.xxx
ip sla schedule 7 life forever start-time now
ip sla 8
 
The actual configuration is as follows:
 
UK00132-DM05-MapleCross#show ip sla configuration 7

Everything was working fine i.e. it was polling the the ip address 195.xxx.xxx.xxx and when the wasn't available I would get a message through my application.
 
However, for some reason the ip sla has stopped working. The interface with ip address 195.xxx.xxx.xxx is down, but the ip sla isn't responding.
 
Is there some kind of timeout?
 
Cheers
