Hello Daniel,

I suppose this is a C6500.

from error message guide 12.2SX

Error Message %IPC-5-WATERMARK:[dec] messages pending in [hex] for the port [chars]


Explanation A particular IPC port is overused. An application is not draining packets quickly, which suggests that the CPU might be busy. [dec] is the number of messages pending in the IPC to be processed by the application. [chars] is the IPC port name. The first [hex] is the IPC port number, the second [hex] is the IPC seat number, and the third [hex] is the IPC index.

Recommended Action Reduce the traffic on this port to a minimal level. If the error message recurs, upgrade the system software to a release containing a fix for Cisco bug ID CSCdw74873 (watermark messages appear continuously with no traffic).

So yes you may need an IOS upgrade

Hope to help
