Hi,


Iam regularly getting the below message in the log of a 6500 sup 720-3b (s72033-advipservicesk9_wan-mz.122-18.SXF10a.bin)


Apr 28 21:21:16: %IPC-5-WATERMARK: 2131 messages pending in rcv for the port Card5/1:Request(2150000.5) seat 2150000.


It doesn't seem to be causing a problem, CPU is OK, and I can't find any bugs directly relating to this. Any ideas.

Hello Chris,

have you got a supervisor in slot 5 ?


How many supervisors are in the chassis ?


IPC should stand for inter process communication and the message should complain of an high number of messages sitting in a queue waiting to be processed or dispatched.


As you have already checked this is the output from error message decoder


1. %IPC-5-WATERMARK: [dec] messages pending in [chars] for the port [chars]([hex].[hex]) seat [hex]


Several IPC messages are waiting to be processed. If the number increases, this condition may result in the exhaustion of IPC header cache or buffers.


Recommended Action: Copy the message exactly as it appears on the console or in the system log. Enter the show tech-support ipc command to gather data that may help identify the nature of the error. Research and attempt to resolve the issue using the tools and utilities provided at http://www.cisco.com/tac. With some messages, these tools and utilities will supply clarifying information. Search for resolved software issues using the Bug Toolkit at http://tools.cisco.com/Support/BugToolKit/action.do?hdnAction=searchBugs. If you still require assistance, open a case with the Technical Assistance Center via the Internet at http://www.cisco.com/cgi-bin/front.x/case_tools/caseOpen.pl, or contact your Cisco technical support representative and provide the representative with the information you have gathered. Attach the following information to your case in nonzipped, plain-text (.txt) format: the output of the show logging and show tech-support ipc commands and your pertinent troubleshooting logs.


It suggests to use

sh tech-support ipc

to get more information


Hope to help

Giuseppe
