Severity

ALERT

Description

This message occurs when the storage system is low in networking buffers (mbuf) for longer than the duration threshold, which indicates abnormal circumstances. When this happens, CLI commands might hang, and clients could experience timeouts.

Corrective Action

If CLI commands are responding slowly or clients are timing out, reboot the node using the "reboot -node [node] -dump true" option. Also call the support team to investigate further, because this is an abnormal circumstance that might recur if not addressed. Contact NetApp technical support.

Syslog Message

exit_percentage (INT): Percentage of in-use mbufs necessary to exit the flow control state.
