As of now, it is not configurable.

If you are not averse to making a code change for your evaluation, you 
can change the value of AFR_POLL_TIMEOUT in 
xlators/cluster/afr/src/afr-self-heald.c to something other than 600.

We will evaluate exposing the interval to be configurable through the 
volume set interface.

Thanks,
