Hello, team!
I have 4500-x switches in VSS. And a few days ago the CPU load completely 50%.
Core 0: CPU utilization for five seconds: 45%; one minute: 40%; five minutes: 32%
Core 1: CPU utilization for five seconds: 56%; one minute: 61%; five minutes: 69%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
5024 1936680 94884962 376 50.82 50.50 50.01 0
IOS XE version - Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.08.01.E RELEASE SOFTWARE (fc2) and uptime is 41 weeks, 3 days, 11 hours, 5 minutes.
Is it possible that the issue with IOS XE version? Is someone has such experience?
in general, i want to make migration from this IOS version to 3.06.06E, looks like it's more stable.
Thank you!

3.6.6 is very stable version across the ios-xe platforms , 3.8.1 is an early deployment you would be better off with the md release the main deployment
there were a few bugs in earlier release for iosd on vss in 4500x it could be a repeat bug or something similar , I checked your release notes below I see some iosd bugs but nothing which relates to high cpu though
unless your hammering the switch its most likely the software and changing it should fix it

does this provide any further info on the process
