It’s probably one of the memory leaks that was fixed in openHAB 2.4.0. You might also want to check if your openHAB is not continuously trying to install some non-existing addon which causes a lot of unnecessary load. See also [[SOLVED] After upgrade to 2.4 stable I'm flooded with java.lang.IllegalStateException](https://community.openhab.org/t/after-upgrade-to-2-4-stable-im-flooded-with-java-lang-illegalstateexception/61567).
