Package: libgdbm6 Version: 1.19-2 Severity: important Dear Maintainer,
I run a few DBM-intensive applications. They manipulate huge DBMs, but they work usually like a charm: 15168 mojolic+ 20 0 90.8g 156260 5460 S 0.0 3.0 0:00.30 known_passwords 15159 mojolic+ 20 0 16.6g 63260 6572 S 0.0 1.2 0:00.15 usenet-fr.pl (as you can see they allocate a lot of virtual memory but do not really make use of it) They usually startup in a few seconds and are very fast when started. They are written in Perl in the Mojolicious framework, I use perlbrew. I just migrated from buster to bullseye and it no longer works at all. The script never complete opening of the DBMs, and uses insanely huge amount of memory (not only virtual). This is the same with the buster-compiled perl-5.36.1-2023-05-14 or with the bullseye just recompiled perl-5.38.0-2023-08-04. However, there is a simple work-around: export LD_LIBRARY_PATH=/home/mojolicious/tmp-libs where this directory contains: lrwxrwxrwx 1 root root 23 Mar 12 2019 libgdbm_compat.so -> libgdbm_compat.so.4.0.0 lrwxrwxrwx 1 root root 23 Mar 12 2019 libgdbm_compat.so.4 -> libgdbm_compat.so.4.0.0 -rw-r--r-- 1 root root 14104 Mar 12 2019 libgdbm_compat.so.4.0.0.O1 lrwxrwxrwx 1 root root 16 Mar 12 2019 libgdbm.so -> libgdbm.so.6.0.0 lrwxrwxrwx 1 root root 16 Mar 12 2019 libgdbm.so.6 -> libgdbm.so.6.0.0 -rw-r--r-- 1 root root 63512 Mar 12 2019 libgdbm.so.6.0.0 As you can see, just overriding libgdbm.so.6.0.0 through LD_LIBRARY_PATH with the buster version of the library is enough (I have tested that renaming libgdbm_compat.so.4.0.0 to libgdbm_compat.so.4.0.0.O1 still fixes the problem, but renaming libgdbm.so.6.0.0 to libgdbm.so.6.0.0.O1 makes the problem reappear). The issue seems to be in the libgdbm6 package, very specifically in libgdbm.so.6.0.0. With the work-around, things seem then to work again like a charm. As an additional note, there seems to have been an issue like this with Fedora: https://github.com/Perl/perl5/issues/18884 They seem to have a patch for GDBM as it is not linked to Perl in any way: https://github.com/Perl/perl5/issues/18884#issuecomment-860437280 Could you look into this? -- System Information: Debian Release: 11.7 APT prefers oldstable-security APT policy: (500, 'oldstable-security'), (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-25-amd64 (SMP w/8 CPU threads) Locale: LANG=C, LC_CTYPE=fr_CH.ISO-8859-1 (charmap=ISO-8859-1), LANGUAGE not set Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages libgdbm6:amd64 depends on: ii libc6 2.31-13+deb11u6 libgdbm6:amd64 recommends no packages.
