First checks

Limit the impact.
Collecting Evidence.
Test the the simplest hypothesis.

Recommended actions

Correct the confirmed cause rather than the symptom.
Document the change and result.
Establish supervision if the defect can recur.

Start Symptom → Cause →

BAOI

Contextual technician plan

Limit the impact.

Identify whether a position, service or entire site is affected.

docker system df.

Expected result

The relevant volume should have sufficient free space for normal operation.

If OK

Capacity is not the immediate blocker; continue with the next hypothesis.

If not OK

Identify what consumes space and free/extend capacity with a controlled change plan.

RiskLow risk / verify context

Collecting Evidence.

Keep the message accurate, time, and associated logs.

Expected result

“Collecting Evidence.” should produce an observation that clearly confirms or rules out “Application volume.”.

If OK

If the observation is normal, lower “Application volume.” in the ranking and continue with the next distinct check.

If not OK

If the observation is abnormal, keep the evidence and investigate “Application volume.” first. Related action: Document the change and result.

RiskManual check

Test the the simplest hypothesis.

Compare with equipment or functional path.

Expected result

“Test the the simplest hypothesis.” should produce an observation that clearly confirms or rules out “Retention.”.

If OK

If the observation is normal, lower “Retention.” in the ranking and continue with the next distinct check.

If not OK

If the observation is abnormal, keep the evidence and investigate “Retention.” first. Related action: Establish supervision if the defect can recur.

RiskManual check

Correct and validate.

Apply only one change at a time and retester.

Expected result

“Correct and validate.” should produce an observation that clearly confirms or rules out the targeted hypothesis.

If OK

If the observation is normal and continue with the next distinct check.

If not OK

If the observation is abnormal, keep the evidence before broader changes.

RiskManual check

✓

Validation after action

Repeat the same validation test after the correction and confirm the original symptom is gone. Validate stability before closing the incident.

↶

Change safety / rollback

Before changing configuration, record the current value and a way back.

When to escalate

Cadader if the impact extends, if the data are at risk or if the cause involves irreversible modification.
