I think "creeping upwards" is a fair description. We have occasionally seen trouble with virt-builder and virt-customize which are using a smallish virtual machine. In Fedora 28+ I have had to increase the memory available to 1G (from 500M previously, note there is no swap) to get package installation to work reliably. I also filed: https://bugzilla.redhat.com/show_bug.cgi?id=1432219 which is closed now, but I think the issue has returned since I closed it. > Anyway, is memory consumption a thing with the new libdnf-in-C++ > efforts? No idea whether rewriting dnf has helped. I'm not clear which version of dnf is the rewritten one. > Could a look into microdnf be a thing for me? For Fedora/RISC-V, in the early days while we were getting all the dependencies for full dnf ready, we used ‘tdnf’ which is another of these cut down solvers (written in C IIRC). I wouldn't recommend that particular program as it has many shortcomings compared to regular dnf. I don't think we tried microdnf however. I think a more productive way to resolve this will be to try to diagnose what's consuming memory. You can probably do this by getting dnf (or python?) to core dump when it runs out of memory, then examining the core dump file for strings to see if you can identify what data is consuming the memory. Another way would be to use an instrumented malloc implementation such as https://github.com/memtt/malt Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com Fedora Windows cross-compiler.
