Bug: `sidecarlogresults` container experiencing persistent high CPU usage

[l-qing]

Expected Behavior

The sidecarlogresults container should have reasonable CPU usage during normal operation. It should efficiently process and store task/pipeline logs without consuming excessive CPU resources.

Actual Behavior

The sidecarlogresults container is experiencing high CPU usage (consistently above 100%) for extended periods, which can impact overall cluster performance and resource availability. This high CPU consumption appears to be persistent and not related to normal log processing activities.

Steps to Reproduce the Problem

1. Deploy a Tekton pipeline
2. Enable results-from: sidecar-logs
3. Monitor the sidecarlogresults container CPU usage using kubectl top pods or cluster monitoring tools
4. Observe that the container maintains high CPU usage even after task completion
