Infinite loading of system virtual machines

[miloserdoff]

Hello. Today I noticed that one of my system VMs (console proxy) is unavailable. Its Agent State was Down. I decided to reboot the system VMs and now they are in the Starting state for a long time.

The Cloudstack Management Server logs said:
WARN [o.a.c.f.j.i.AsyncJobMonitor] (Timer-0:[ctx-e8343f22]) (logid:fed07982) Task (job-389) has been pending for 1618 seconds
WARN [o.a.c.f.j.i.AsyncJobMonitor] (Timer-0:[ctx-e8343f22]) (logid:fed07982) Task (job-390) has been pending for 1618 seconds

Now, they are still in the Starting state.

I decided to check other functions of this host, and saw that I can't view the contents of the NFS server:
ERROR [c.c.a.ApiServer] (qtp1404565079-82973:[ctx-1d9fd248, ctx-eddcf4ec]) (logid:c913a3ec) unhandled exception executing api command: [Ljava.lang.String;@1863a332 com.cloud.utils.exception.CloudRuntimeException: No remote endpoint to send command

Please tell me how to solve the problem and restore the host's functionality?
