Description

The scheduler can log a panic when the logging system tries to log a nil resource.
An example for a log entry:

2020-10-10T01:57:55.882Z	ERROR	cache/queue_info.go:261	parent queue exceeds maximum resource	{"allocationId": "map[memory:1]", "maxResourceError": "PANIC=runtime error: invalid memory address or nil pointer dereference", "error": "allocation (map[memory:1]) puts queue root over maximum allocation (map[attachable-volumes-aws-ebs:475 ephemeral-storage:-528315005700 hugepages-1Gi:0 hugepages-2Mi:0 memory:1898860 pods:3450 vcore:264875])"}
