%SIBYTE-6-SB_RMON_OVRFL : RMON register [dec] overflow on mac [dec]

from 6513 logg:

14w3d: %SIBYTE-DFC9-6-SB_RMON_OVRFL: RMON register 20 overflow on mac 1

14w3d: %SIBYTE-DFC13-6-SB_RMON_OVRFL: RMON register 20 overflow on mac 1

14w3d: %SIBYTE-DFC12-6-SB_RMON_OVRFL: RMON register 20 overflow on mac 1

14w3d: %SIBYTE-DFC10-6-SB_RMON_OVRFL: RMON register 20 overflow on mac 1

14w3d: %SIBYTE-DFC11-6-SB_RMON_OVRFL: RMON register 20 overflow on mac 1

Cisco documentation describes this as "Explanation - An RMON register has wrapped around."

My question to the forum is, how severe is this and where can I look to determine the cause (and possible fix if it's serious) of this issue? The switch is still functioning properly and all trends remain the same (traffic patterns, cpu, etc).

Any help is appreciated.

Thanks,

Kyle

Also, the DFC cards referenced are all identical, here is partial output from sh module:

Like I said, everything seems fine and that message is about a week old now, but I'm just paranoid and wanted some feedback.

Thanks!

Kyle,

Looks like you are hitting bug CSCsa53954. We've seen this on 6509's, but didn't appear to be affecting anything. You may want to open a TAC case.

More details at:

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsa53954

Hope this helps. If so, please rate!

Thanks,

Kevin
