I will analyze those logs once you share them. Comparing two snapshots from different Squid versions/instances may be useful, but it is much more time consuming, and I cannot offer to do that right now. > The output appears to be quite large > ... where do I send the files with the memory logs? The scripts that track memory usage changes across hourly snapshots do not care about the log size. However, you may want to share a link to the (compressed) log rather than sharing the log itself. The best place to share that info, IMO, is the bug report I referenced above, but you can post here, of course. > I might have to fix how it is launched from > the docker entrypoint script in my test env. FWIW, here is one of the valgrind commands I use (with paths stripped): > valgrind -v --trace-children=no --child-silent-after-fork=yes --num-callers=50 --log-file=valgrind-%p.log --time-stamp=yes --leak-check=full --leak-resolution=high --show-reachable=no --track-origins=no --gen-suppressions=all --suppressions=valgrind.supp squid -f squid.conf ... Valgrind reports useful leak info after Squid exits. I do not have updated/polished Valgrind suppressions, but I can share what I use: https://gist.github.com/rousskov/a1f503981b4a3832ab44221b0b615b5a I do not use gdb/valgrind monitor so I cannot help you there.
