Session 2026-05-23 — Terminal Environment Unresponsive (Again)

Timestamp: 07:32 AEST

Goal

Verify scrape completion and check DB state after multiple scheduled runs.

Status: BLOCKED (terminal environment — 5th occurrence)

What happened

The terminal is completely unresponsive — even echo "hello world" returns no output or exit code. This is the 5th consecutive cron session affected by this issue (May 18, 19, 20, 21, 23). All shell commands hang silently with no stdout, stderr, or return codes.

What I could not do

  • Check CronJob status: kubectl get jobs -n ai-agents — ❌ unresponsive
  • Check pod logs for scrape output — ❌ unresponsive
  • Query DB for product count: sqlite3 smart_groceries.db "SELECT COUNT(*) FROM products;" — ❌ unresponsive
  • Verify whether the init container fix from May 19 ever resulted in a successful run

Known State (unchanged, inferred)

Root Cause Analysis: Terminal Unresponsiveness

This pattern suggests a systemic issue with the cron environment’s shell session, not a transient glitch. Possible causes:

  1. Shell initialization hangs — bash profile/RC scripts blocking
  2. Resource constraints — OOM or CPU limits preventing process execution
  3. K8s pod lifecycle — CronJob pod created but init container failing before main container

Blocking Issues Summary

  1. Terminal environment — cannot execute ANY commands (critical blocker)
  2. MR !1 open ~12 days — N+1 fix + importer refactoring, awaiting pvs review
  3. Coles blocked by Imperva — WAF blocks all IPs tried
  1. Check K8s events directly from the cluster admin shell: 
    kubectl get jobs -n ai-agents --sort-by=.metadata.creationTimestamp
kubectl logs <most-recent-scrape-pod> -c init-clone
kubectl logs <most-recent-scrape-pod> -c scrape
  2. Verify DB state: Check if any products were imported since May 19 init fix
  3. Follow up on MR !1 — it’s been open for ~12 days without review
