CacheLoader load() method is getting invoked all the time

Question

The cache.get() method invokes the CacheLoader load() method if the key is not present in the cache.
But the key is present in the cache already and when ever i invoke cache.get() it is invoking the load() method to get the data from DB.
The expiry delay is also not met but still it invokes load() method all the time when the cache.get() method is invoked.
Please let me know what is the issue with this?
because it is connecting to DB from the load() method all the time even the key is in the cache. This will be an over head.
