After the CloudForms 3.2 migration, automation code threw the following exception when executing a best_fit_code method for bulk provision testing: “0x000... is recycled object”
This was because previous version of CloudForms used its own caching mechanism to cache objects sent as references to the Automate Methods. The DRb recycled object errors were caused since some of the objects which were sent as references were not being cached. DRb has a built in caching mechanism based on TimerIdConv, which is now being implemented with this patch. This, as a result, has now resolved the issue.
