Large agent trace files cause OOM errors despite file count limits

By PulseAugur Editorial · [1 sources] ·

A developer encountered an Out-Of-Memory (OOM) error while validating large agent-trace corpora for the AgentWatch project, despite setting file count limits. The issue stemmed from a single 590 MB parquet file containing only 100 rows, with each row averaging 5.9 MB of text data. The validator's process of loading entire parquet files into memory and then converting them to Python objects caused a significant memory expansion, leading to the VM being killed by the OOM killer.

    I OOM'd on 100 Rows Because One File Was 590 MB

    <p>My validator got SIGKILL'd on 100 rows. Not 100 million — a hundred. And I'd already done the responsible thing and capped how many files it reads.</p> <p>The cap bounded file count, not file size. One 590 MB parquet file defeated it, and 100 rows took down a 7 GB VM.</p> <p>T…
