Hi All,
Our client is encountering high CPU utilization of almost 100% on his Cisco 6509-E. When I checked the "show process cpu" the process "ios-base" constitutes to 97% of that utilization. The IOS version that they are using is s72033-ipbasek9-vz.122-33.SXI2a.bin. Is there a known bug for this IOS? I'm trying to look for it at cisco.com but can't find any that will relate to ios-base process.
Thanks in advance for your help.

Hi,
It may be happening because of traffic hitting CPU. Follow these steps to troubleshoot it:
sh process cpu
- check the PID for IOS-base
tHEN DO "show process cpu detailed x" (WHERE X is process from above)
See which process is taking most and let us know.
It will be also helpful to collect traffic hitting CPU. The commands below are non-intrusive:
debug netdr cap rx
show netdr cap
u all

maybe it would be better to use "mz" ios instead of "vz" ios. As i remember, in modular ios more one process seems bundled as one process (like ios-base) in cpu outcome. So it can be difficult to analyse problems.
