Two production locking incidents run down under emergency cover, then eight cores taken off the yearly bill
The call. A firearms maker on an over-provisioned production server had that box seize up twice inside a short stretch, and each time the application stalled hard behind it. Abandoned and resource-hungry sessions were parked on the instance, sitting on locks and starving everything queued up behind them, while the alert channel buried any real signal under noise. The same box had also been handed 24 vCPUs it was never coming close to using.
What we did. A senior DBA took it on an emergency call, worked each of the two incidents back to the sessions driving them, and killed the abandoned and runaway work so the application could move again. Once the instance sat steady, we measured what the workload genuinely needed and put a right-size on the table: drop from 24 vCPUs to 16, with the yearly licensing and compute saving written out in full.

Where these come from. The two-incident count and the 55% fall in alerts are read straight off the client's monitoring on either side of the emergency. The 24-to-16 core figure is the right-size we recommended after watching the real workload, and the annual saving follows from eight fewer licensed cores.
The outcome. Both incidents closed out on that one emergency engagement, throughput came back to the application, and the alert channel dropped by better than half once the runaway sessions were gone. Trimming the instance to 16 cores pulls genuine licensing and compute cost off the annual bill while the workload keeps running the way it did.
The technical detail
What the emergency turned up. Two separate locking events traced back to abandoned and resource-heavy sessions that grabbed locks and held the rest of the workload behind them, and the same server had been over-provisioned at 24 vCPUs for a load that never demanded them.
How we handled it (identifiers generalized for privacy):
-- Two locking incidents: abandoned + runaway sessions holding locks.
-- Traced the blocking chain, then terminated the offending sessions:
KILL <abandoned_spid>; -- repeated per session on the chain
-- workload then sized; right-size recommended 24 to 16 vCPUs
With the runaway sessions gone the blocking chain broke and throughput returned, the alert channel settled about 55% lower, and the sized-down 16-core instance carries the same load for less money.
