Technical Background

Error message issue of ‘Could not spawn…’ can be a result of low system resource

Windows resource is more than just CPU, memory & disk space

There is internal resource such as ‘heap’ and more which was uncommonly discussed

There was case study showing VM Guest Tool not up-to-date caused network driver leaks on system resource under no CPU and memory stress

It is completely a Windows behavior

Resolution

Plan for server restart
