# From time to time:
logging.debug(mem_top()) # Or just print().

Explaining result:

• Noticed a leak of 6GB RAM and counting.

• Added “mem_top” and let it run for a while.

• When got the result above it became absolutely clear who is leaking here - the Python client of Gearman.

• Found its known bug - https://github.com/Yelp/python-gearman/issues/10 leaking defaultdict of deques, and a dict of GearmanJobRequest-s, just as the “mem_top” showed.

• Replaced “python-gearman” - long story: stale 2.0.2 at PyPI, broken 2.0.X at github, etc.

• “mem_top” confirmed the leak is now completely closed.

Config defaults:

mem_top(limit=10, width=100, sep='\n', refs_format='{num}\t{type} {obj}', types_format='{num}\t {obj}')
