When new worlds are created, an integer is incremented. When this integer overflows, the kernel panics and fails with a purple diagnostic screen. In ESXi, new worlds are created for all processes because there is no service console operating system. Therefore, this number increments much faster in ESXi than ESX. In ESXi, this issue occurs when the system has been running for a very long time (over a year) without a reboot and has been actively creating processes. In ESX classic, it is almost impossible to hit this threshold.


This issue is resolved in the following ESX/ESXi releases:

Note: This issue does not affect ESXi 5.1

If you are unable to upgrade to the appropriate release, to workaround this issue on earlier release of ESX/ESXi, reboot the host. Rebooting the host restarts the counter and eliminates the risk of any failure.
To avoid a reboot, you can check to determine if your system is at risk.
To determine if your system is at risk, run this script in the ESXi command line:

ps -c  | awk {'print $1'} | sort -n | tail -n 1
If the output returns a value of 100,000 or above it is recommended to schedule a reboot.
