Thanks, it appears to be crashing when the vhclientx86_64 daemon is exiting. Are you calling vhclient_x86_64 -t exit? Did you purchase a license for the virtualhere server?

No,  client runs as service.
Unfortunatelly, I dont have access to server side and license info

vhclientx86_64 -t '"LIST LICENSES"

Return me the output of that
