Hi Jaicel,
please attach agent.log and broker.log from the host where you trying to 
run hosted-engine --vm-status. I have a feeling that you ran into a 
known problem on gluster - stalled file descriptor, in that case the 
only known solution at this time is to restart the broker & agent as you 
have already found out.

Regards,
Jirka
