Host ramdisk file table limit exceeded
If the files were created by administrative action (for example, accidentally copying files to an incorrect path), then remove the files.
The following command shows the ramdisks’ mount points in vSphere 5.1:
esxcli system visorfs ramdisk list
This might be helpful in locating extraneous files. If the normal operation of the system appears to cause the error, then contact VMware support.
