Workaround:
Reloading effected AS9k-8T-L line card via "hw-module location x/y/x reload"
Further Problem Description:
If the issue reoccurs, collect command as specified in the "Cmds to be captured" attachment and contact the DE community time for further actions, which will help in root causing the issue.
I realized that IOS-XR 4.2.3 code seems to be hit by this bug. Please is the above workaround also applicable for the 4.2.3 code?
