vCenter Appliance loses password?

[CTSTech]

We  have a vCenter 5.1 Appliance VM that seems to lose its Root password  every few days and our backups start to fail.  We try to log in as Root  and get an "incorrect username or password" error.

We  then have to log into an ESXi host and restart the vCenter VM.  After  the vCenter reboots, we can log into it again with Root.

Any ideas?

How are you logging into the VC? Using vSphere client or PUTTY when it stops taking the backup? Could you share the VC log bundles?

When it stops taking the backup, we cannot log into VC using the vSphere client.  We have not tried putty.  Attached is the log bundles.

vpxd is crashing. Hence the issues.

What it looks like are multiple collect attempts to the VCVA
