HI, Have already someone seen a null pointer when deleting a VM?
I have and environment running for a while with CS 4.3.1, and today I tried to delete a VM that was in expunging state but it keeps getting an error: 2014-11-06 10:54:23,473 DEBUG [c.c.v.VirtualMachineManagerImpl] (Job-Executor-37:ctx-0dd66018 ctx-086a8303) Cleaning up hypervisor data structures (ex.
