Not sure if we have a good howto on watching for memory leaks. But you could run something like "sudo pmap [pid]" and watch it over time (like several days). Expect some fluctuations for load. You may find a dependent library that has an issue.
Others may have better tools that are commonly found on Linux. Some additional tools you can download: https://www.baeldung.com/linux/memory-leak-active-process [https://www.baeldung.com/wp-content/uploads/sites/2/2021/09/Featured-Linux-6.png]<https://www.baeldung.com/linux/memory-leak-active-process> How to Find Memory Leak of a Running Process in Linux<https://www.baeldung.com/linux/memory-leak-active-process> The top and htop commands both provide a high-level view of system resource usage, including memory consumption. htop is a better version of the top command that is interactive and more informative.These tools are particularly useful for quickly checking if a process is consuming too much memory over time. We’ll focus on htop for now, which can be installed using apt: www.baeldung.com Robert Wagner ________________________________ From: bind-users <bind-users-boun...@lists.isc.org> on behalf of Ondřej Surý <ond...@isc.org> Sent: Thursday, February 13, 2025 4:33 AM To: Borja Marcos <bor...@sarenet.es> Cc: bind-users <bind-users@lists.isc.org> Subject: Re: Just a suspicion for now: Memory leak in 9.20.4? This email originated from outside of TESLA Do not click links or open attachments unless you recognize the sender and know the content is safe. The increase could be for various reasons. The query pattern is different, the underlying database is different, the other data structures are different. Unless there’s unbounded growth (in the stats), or the cache memory goes over configured limit, there’s nothing to worry about. Sometimes it is possible to have smaller and faster, sometimes the smaller even means faster, but there are times where faster means larger.
