HP ProCurve Switch: Deleted corrupted packet buffers Health Monitor

Jalasoft.Xian.SmartManagementPacks.HPProCurveSwitches.DeletedCorruptedPacketBuffers.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Deleted corrupted packet buffers if has changed its state.

Knowledge Base article:

Summary

Number of deleted corrupted packet buffers is over threshold.

The number of corrupted packet buffers that were deleted is above the maximum threshold configured in Xian Network Manager 2012.

Causes

The switch is detecting a large amount of corrupted packet buffers. This vulnerability is likely due to a memory corruption bug, and may be an exploitable buffer overflow.

Resolutions

An excessive amount of corrupted packet buffers may lead to a traffic slow down. Analyze the buffer strategies for handling message buffers and perform buffer tuning, if necessary.

Additional

Monitors the number of times a corrupted packet buffer has been deleted.
