# Expected Behavior

# Actual Behavior

# Steps to Reproduce the Problem

1.The local console can print logs to check the execution of the pipeline（tkn pipeline start ...... --showlog）
2.After many times of execution（tkn pipeline start ...... --showlog）, the local console suddenly has no logs
3.Change to a different system and execute. At first, there was a log, but it stopped printing after a while

# Additional Info
The console can print logs after adding -- showlog in the earlier stage. However, after a period of time, the console suddenly stops printing logs, but the pod corresponding to pipelinerun still has logs.

tkn pipeline start --filename builds/tekton/build/unittest_main.yaml --param [email protected]:re/rx.git --param gitrevision=add_tekton_0908 --param cov-flag=false --param module=all -w name=shared-data,volumeClaimTemplateFile=builds/tekton/build/workspace-template.yaml -w name=gitlab-release-credentials,secret=gitlab-release-credentials --pod-template builds/tekton/build/pod-template.yaml -k /home/jenkins/workspace/workspace/re_dept/debug/whh_debug/test_config/config --pipeline-timeout 15m -n tekton-pipelines --showlog

[whhx]

The logs can be viewed through tkn pipeline logs xxx, but after adding -- showlog to the local console, after a certain number of executions

I'm using tutorial from here: https://redhat-scholars.github.io/tekton-tutorial/tekton-tutorial/tasks.html using:

minikube version: v1.28.0
kubectl and kubernetes: v1.23.3
tkn version                       
Client version: 0.27.0
Pipeline version: v0.24.3
Dashboard version: v0.30.0

running:

 tkn clustertask start echoer --showlog
TaskRun started: echoer-run-nmqr9
Waiting for logs to be available...
task echoer create has not started yet or pod for task not yet available

No output at all.

But logs do exist:

kubectl logs echoer-run-nmqr9-pod-5fstw --all-containers
