Change VPG recovery host failure

I have a tickets logged for this which is currently waiting on VMware but was wondering if anyone else is seeing this issue?

I have quite a large VPG with 50 disks and moving the VPG from one host to another fails almost every time and rolls back.  I don’t see the issue with smaller VPGs.  This is via the Change Recovery Host option or editing the VPG and changing the recovery host – same result.

The error I see (in the host I am trying to move from) vmkernel.log is this when it fails:

vpxa-worker: Directory changing too often to perform readdir operation (11 retries), returning busy.

Googling this error brings up some old post about NFS but nothing of use.

Thanks
