Sorry, I do not know much about pprof. The graph shows that 200MB out of
500MB was allocated to close callbacks for deferred reads (the current
suspect), right? Is there an indication that those objects were actually
leaked?

How long did this test run, and does the 200MB/test_time memory
consumption speed correlate with what you have observed in longer tests?

Finally, the other 300MB are due to pooled allocations. Those are
tracked and reported by cache manager. Do you see any abnormal memory
stats when you query your longer-running Squids?

Thank you,

Alex.
