Description

If processing of update on NN takes more than the cache interval time(default:30 secs), it is possible that two updates will be processed parallely leading to unexpected behavior. We should instead lock the processing of updates so that we ensure they happen sequentially. Also while doing so, we should add a flag to make sure we should never go into stale mode while processing an update.
