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?
