Symptoms
The following symptoms can be used to determine if we are in a kernel memory shortage situation :
When a memory shortage occurs, the system typically collapses this way:
- Data services become unavailable,
- The BUI and CLI are unavailable also.
- A connection to the ZFSSA through SSH is impossible.
- Any connection to the ILOM of the ZFSSA through SSH, then starting the console shows no prompt at all.
Those are the typical symptoms helping to determine we are in a kernel memory shortage situation.
Changes
This can happen while no recent change has been committed to the system recently.
