NetFlow exporter stops sending packets

Have a Cat 4507 with Supervisor 7-E, setup configuration to send NetFLow information to an external server, everything worked great but after 2 weeks, the exporter is showing zero packets sent and the following error is at the console:

Nov  5 15:52:35.231: %C4K_HWFLOWMAN-3-NFEINTERRUPTSTATUS: (Suppressed 7336 times)module: fi InterruptStatus: 0x4

Nov  5 15:53:05.235: %C4K_HWFLOWMAN-3-NFEINTERRUPTSTATUS: (Suppressed 7345 times)module: fi InterruptStatus: 0x4

Nov  5 15:53:35.239: %C4K_HWFLOWMAN-3-NFEINTERRUPTSTATUS: (Suppressed 7341 times)module: fi InterruptStatus: 0x4

Nov  5 15:54:05.243: %C4K_HWFLOWMAN-3-NFEINTERRUPTSTATUS: (Suppressed 7344 times)module: fi InterruptStatus: 0x4

Nov  5 15:54:35.247: %C4K_HWFLOWMAN-3-NFEINTERRUPTSTATUS: (Suppressed 7341 times)module: fi InterruptStatus: 0x4

4507#show flow exporter statistics

Flow Exporter Netflow-to-Orion:

  Packet send statistics (last cleared 01:08:30 ago):

    Successfully sent:         0                     (0 bytes)

  Client send statistics:

    Client: Flow Monitor NetFlow-Monitor

      Records added:           0

      Bytes added:             0

I can't find any information related to that error, I haven't restart the switch because this is a very critical switch on a production network and also I would like to do some troubleshooting before doing an IOS upgrade or hardware replacement.

Any ideas?

I'm seeing the exact message and have not been able to find anything on it either. But I'm not running Netflow.

Which IOS version and Supervisor are you running?

Mine is:  

  • cat4500e-universal.SPA.03.02.00.SG.150-2.SG.bin

  • WS-X45-SUP7-E

Still haven't been able to find any information about the error.

Hello,

Same here. We have encountered this bug with our CAT 4507 SUP7E.

Our current IOS version is:  cat4500e-universal.SPA.03.01.01.SG.150-1.XO1.bin.

Netflow collector can not collect any flow from this switch anymore, and CPU of 4507 always reaches over 50%.

Did anyone also face this error? After reboot, will the 4507 and its netflow work well ?

Thanks

I've reloaded this switch for a few days and it's worked fine since then. Hope that I'll never encountered this bug again.

We're seeing the same issue on a 4506E Sup7e and cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin.

Has this been fixed yet? CSCub56668 suggests not and CSCtq40467 is restricted so I can't read it.
