visorfs.ramdisk.full

Problem Fairly recently I came across this error message on one of my hosts “esx.problem.visorfs.ramdisk.full” Fallout While trying to address the issue I had the following problems when the ramdisk did indeed “fill up” PSOD (worst case happened only once in my experience) VM’s struggling to vMotion from the affected host when putting into maintenance mode. Temporary workaround A reboot of the host would clear the problem (clear out the ramdisk) for a short while but the problem will return if not addressed properly.
