Cat6500-SUP32/MSFC2A modular IOS - High Memory Utilization

[sg37868]

Hi all.

We have a Catalyst 6500 with SUP32/MSFC2A. Currently we're testing modular IOS (12.2(18)SXF12 ipbasek9).

While testing, we are experiencing a permanent high memory utilization (92%) of the I/O Mempool without any traffic on the device.

With non-modular IOS (same Version, same config)utilization of I/O Mempool is only 16%.

Memory-Historie of modular and non-modular IOS can be found in the attachment.

Any ideas or hints?

Thanks.

Sebastian

Issue seems to be solved in IOS 12.2(33)SXH.
