Hi,
Yesterday without any warning one of our VMs crashed unexpectedly.
In the Windows event log there is nothing (only the system shutdown was unexpected).
In the vcenter the error is: Error message from vmhost: VMware ESX unrecoverable error: (vcpu-7) MXUserAllocSerialNumber: too many locks!
In the vmware-12.log I found this:
