Explanation
If this message appears continuously, it indicates that the fdbAgeTask is using most of the CPU power.
It is most likely caused by a problem within the network (such as, broadcast storm, packet storm).
If this message appears occasionally, it indicates that the task consumed high CPU cycles at some point
in time. As a result, you see an increase in fdbAgeTask number.
This error occurs on switches with multiple MAC addresses that are associated with IP FDB entries.
Upon aging the MAC addresses according to the user-specified MAC aging timer, the system becomes
unresponsive because the MAC entries have been flushed from the database. Subsequently, this
message is printed in the log indicating that the fdbAgeTask consumed a high amount of CPU power.
Action
If this message appears continuously, check the network topology and ensure that no loops exist in the
network. Check port statistics to determine where heavy traffic is coming in.
If you are using ExtremeWare 6.1.5b20 or earlier, upgrade to the latest software.
If this message appears occasionally, no action is necessary.
