Abstract—One of the most important goals for companies that provide cloud computing services is to maintain high availability on large computer systems. Therefore, to accomplish such objective it is necessary to determine the main causes and the main problems associated with it. Many of these problems are related with software failures, for instance software aging. Software aging is a degrading factor in systems, leading to software failures, poor performance and may result in system downtime. This paper investigates the software aging effects on the Openstack cloud computing platform. The environment was tested using a stressful workload, and monitored through Bash scripts that collects information about the utilization of hardware resources, as well as information about processes related to the platform. The results indicate software aging issues in the MySQL process; a growth on the memory consumption was detected, and a prediction analysis was also used to estimate the resources utilization in the future.

Index Terms—Cloud computing, memory leaking, openstack platform, software aging.
