Dmytro Sadovnychyi created BEAM-7279:
----------------------------------------
Summary: Huge memory leak when using logging with invalid params
on py27
Key: BEAM-7279
URL: https://issues.apache.org/jira/browse/BEAM-7279
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Affects Versions: 2.12.0, 2.11.0
Environment: macos, beam 2.11.0
Reporter: Dmytro Sadovnychyi
This very exotic and invalid input to log function causes the memory usage go
all the way up until it's killed by OS (so the worker dies with OOM).
```
import logging
import apache_beam as beam
[0] | beam.Map(lambda x: logging.warning('%203080000332%', 1))
```
Works as expected on python37 (raises TypeError), fails on python27 on macOS,
linux and dataflow workers.
