Core issue

The error message seems to be

%SYS-3-SEM_HOLDMANY:Task [Chars] holds too many semaphores

This message indicates that a task is holding too many semaphores. [chars] is the name of the task.

The message is an indication that the EtherChannel process has locked a couple of memory blocks for its use. The error message is generated when this occurs since there is a chance that other processes may run out of memory blocks to use. If the message is continuously scrolling through, then it can be a problem with the EtherChannel using too much memory.

This message is mostly cosmetic and does not affect the switch's functionality.

Resolution

If this message comes up continuously, then a possible solution is to clear the EtherChannel configuration and re-configure it during a maintenance window.

For more information on how to configure EtherChannel on Cisco Catalyst switches that run CatOS system software, refer to the article How to configure EtherChannel on Cisco Catalyst switches that run CatOS system software.
