Summary

Free buffer elements is under threshold.

The number of available buffer elements is below the minimum threshold configured in Xian Network Manager 2012.

Causes

Resolutions

Analyze the buffer strategies and perform buffer tuning, if necessary. Sometimes it can be solved just by updating your Cisco IOS. Use 'show buffers old' command to get more information and find the problem.
