A computer-implemented method according to one embodiment includes determining, using a nanoservice in a first cluster, whether a microservice of a second cluster has restarted. In response to a determination that the microservice has restarted, an external job service is informed about the restart of the microservice and a job associated with the microservice is caused to be reset. A computer program product according to another embodiment includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and/or executable by a computer to cause the computer to perform the foregoing method.

A computer-implemented method, a computer program product, and a computer system for determining origins of memory leaks in source code. A computer system writes a first memory dump, in response to a memory leak being detected. A computer system searches the first memory dump to determine types of suspect leaking collections. A computer system creates identifiers for respective instances of each of the types. A computer system writes a second memory dump, in response to a continued memory leak being detected. A computer system determines which unique identifiers from the second memory dump correspond to growing collection objects of the types. A computer system tracks code paths of calls that add objects to collections whose identifiers match one of the unique identifiers. A computer system logs the code paths for review by developers.

Terminating and serializing HTTP load is provided. The method comprising receiving, by a load balancer, a client request. An HTTP parser in the load balancer is invokes, which parses the client request. A lambda function in the load balancer is then invoked, wherein the lambda function specifies data format requirements for a language used in a backend server. The load balancer parses the client request according to the lambda function in a manner specific to the language used in the backend server. The load balancer then serializes the client request according to the lambda function in a manner specific to the language used in the backend server. The load balancer sends the serialized client request to the backend server.

By analyzing a test case in a set of test cases, the test case is classified into a test type. Using a result of analyzing a test execution environment, a flake parameter is set, the flake parameter comprising an execution environment characteristic capable of causing an inconclusive result of execution of the test case. Responsive to determining that the test type maps to the flake parameter, the test case is removed from the set of test cases, the removing resulting in a filtered set of test cases, the determining performed using a predefined set of mappings. The filtered set of test cases is executed in the test execution environment.

An approach is provided for optimizing a just-in-time (JIT) compilation process. A source pod in a container orchestrated execution environment is determined to be saturated. Profile data from a JIT compiler, a virtual machine state, and a native-compiled code state are collected. The profile data, virtual machine state, and native-compiled code state are stored in a data structure in a persistent data repository. In response to a restart or a redeployment of the source pod and an application running on the source pod, the stored profile data, virtual machine state, and native-compiled code state are reused in a new target pod, without requiring a monitoring and an identification of hot code areas in the application after the source pod becomes saturated.

Execution of varying tasks for heterogeneous applications running in a single runtime environment is managed. The runtime environment is capable of managing thread pools for any of the plurality of applications and receives a request to manage a thread pool for one of the applications. The request includes size thresholds for the pool, a first function to be invoked for creation of threads, and a second function to be invoked for termination of the threads. Responsive to detecting that a first size threshold is not satisfied, the runtime environment invokes the first function to cause the application to create an additional thread. Responsive to detecting that a second size threshold is not satisfied, the runtime environment places an artificial task that incorporates the second function into a work queue for the thread pool, whereby a thread executes the artificial task to invoke the second function and thereby terminates.
