#1844 model method run with ~100MB stdout hangs/times out

Opened by stack72 · 8/26/2026

Summary

Running a model method that produces ~100MB of stdout (1M lines × 100 chars via yes ... | head -n 1000000) causes the swamp process to hang or take excessively long, timing out the 5-minute CI job (runner killed with SIGKILL, exit code 143).

Impact

The UAT test swamp model method run handles large stdout without crashing in Tier 4 (resource exhaustion) consistently times out in CI.

Expected behavior

Swamp should handle large stdout from model methods without hanging. The process should complete within a reasonable time, even if the output is large.

Repro

  1. Create a command/shell model with: yes 'aaa...aaa' | head -n 1000000 (100-char line × 1M lines ≈ 100MB)
  2. swamp model method run <model> execute
  3. Process hangs or takes >5 minutes
