I find the problem
problem was manage IP in vcenter , the manage IP must be set to Vcenter machine IP address after connect to esx  /etc/opt/vmware/vxpa/vxpa.cfg will be update with this IP as a ServerIP Address .

Like this :  <serverIp>172.16.117.10</serverIp>

It's very important config for have a stable connection between vcenter and esx server .

Thanks a lot
Behnam

Can you connect to the host directly with the Client? Does it disconnect with direct connection like it does when connected through vCenter?

When at the logon screen for the vSphere Client, you type the IP or hostname of the ESX server and logon using the root account (or if you created another acct, you can logon with that).

"Mapnaturbine"....I'm NOT asking if you can connect to your host through VCENTER...I'm asking if you can connect to your host DIRECTLY, as I described above - with the IP/hostname of your ESX server in the vSphere Client, NOT the IP/hostname of your vCenter server. Can you connect directly, and if so, do you get disconnected logging in directly as well?

I am so sorry my friend :)
no when in connect directly I don't have any problem and the connection is stable but in this way  I can not fully manage the server .

OK...yeah...I know you can't fully manage it. I was just wanting to test the different connection scenarios. So, the problem seems to stem from the 'agent' vCenter places on the host to manage it. At this point, I'm out of suggestions on what to look for/suggest to fix. You can try to look at log files under the Home -> Administration -> System Logs section of your vSphere Client when logged into the host, although you may lose connection to the host while trying to do so. If the logs do not provide any further information on resolution, I suggest contacting VMWare, if you have a support contract with them.
