> When node is halted during saving stored cache data, content of this file can be corrupted. 
> 1. Additional check should be implemented in FilePageStoreManager.readCacheData  
> (print the name of corrupted file)
> 2. In storeCacheData we need to serialize StoredCacheData to temp file then swap.
