A system and methods of managing entries in a cuckoo hash table that is subject to manipulation by a plurality of concurrent processors are provided. The cuckoo hash table is used to maintain a plurality of keys, along with their data items, in a plurality of entries. In accordance with an operating method, a first command for the cuckoo hash table is processed, and the first command is associated with a first processor of the plurality of concurrent processors. In addition, invalid conditions associated with concurrent processing of a second command for the cuckoo hash table are prevented or minimized. The second command is associated with a second processor of the plurality of concurrent processors. As one example, the operating method manages the situation where concurrent push commands create a race condition. As another example, the operating method manages the situation where a lookup or delete command from one processor competes with a push command from another processor.
