Should my application be cycling even if it receives steady traffic? I average about 1 hit per second, yet my app seems to bootstrap several times every hour at an erratic rate.
Appid is mobca-st. Look in the logs for "ConfigurationBootstrap" at level Info. This is the Resteasy bootstrap. The cycling seems to happen all the time with no obvious reason. The only heavy framework (ie, that does classpath scanning) is Resteasy. It doesn't even use JDO/JPA. Startup time is usually 10-15s.
