Infinite call loop prevention system

Systems and methods of identifying infinite call loops using custom tracking headers are provided. In one exemplary embodiment, a method is performed by a first instance of a microservice operated by a first network node in a distributed microservice system having instances of one or more microservices operated by network nodes with each instance having a data cache operable to share data between instances of that microservice. The method includes receiving an indication that includes a message to access data that may be available in a data cache of an instance of the microservice, the indication also including one or more tracking identifiers with each tracking identifier corresponding to an instance of the microservice that successively sends or receives the message so as to determine that the message corresponds to a same message previously sent or received by the same instance of the microservice.
