ESXi5 – management services crashes – vms running

I have a setup with two ESXi5 servers.

We are(were) running with a ISCSi box to server disk for the VM's – however we are in the progress of migrating away from it, because the storage os disk is bad.

Now, one of the ESXi hosts has been running for ~20hrs, and it seems like the management services just crashed on that host..

The vms are still running – so it's not really serious. However, I want to fix it.

Should I be worried? Will the VM's keep running?

The hosts does respond on pings.

I am running a vcenter to administrate the hosts.

Thanks in advance.

UPDATE:

I have now managed to get the services running:

~ # /etc/init.d/vpxa status
vpxa is running
~ # /etc/init.d/hostd status
hostd is running.

But the server is still not responding on either VMware vSphere Client nor the webinterface.

I can however use paping on both port 80 and 443 to the server, which works brilliant.

I would like some help to move on in this case.
