Hi Dag, Yes you are right it was the only problem - OpenJDK 1.8
1. i removed the cloudstack agent and OpenJDK 1.8. 2. i removed the host for tests. 3. i installed the OpenJDK 1.7.X Patchlevel and installed cloudstack agent again. 4. add host back to cloudstack management. Alert is gone after any seconds. After that all things run fine. Thanks and Regards, Sven -----Ursprüngliche Nachricht----- Von: Dag Sonstebo [mailto:[email protected]] Gesendet: Montag, 21.

Once host was downgraded to OpenJDK 1.7 the issue seemed to be resolved. Sven – if I missed any steps you carried out can you update?
