[Aptitude-devel] Bug#373846: aptitude: Resolving dependencies uses all system memory

[Vincent Lefevre]

Package: aptitude
Version: 0.8.13-8.1
Followup-For: Bug #373846

Same problem with "U" to upgrade from the TUI. After several minutes,
aptitude takes all the available memory (around 28 GB!) and is killed
by earlyoom:

Ouch!  Got SIGTERM, dying..

In the journalctl logs:

Sep 24 00:34:10 qaa earlyoom[1260]: mem avail:  1047 of 30328 MiB ( 3.45%), swap free:   82 of  975 MiB ( 8.45%)
Sep 24 00:34:10 qaa earlyoom[1260]: low memory! at or below SIGTERM limits: mem 10.00%, swap 10.00%
Sep 24 00:34:10 qaa earlyoom[1260]: sending SIGTERM to process 848416 uid 1000 "aptitude": oom_score 1246, oom_score_adj 0, VmRSS 28302 MiB, cmdline "aptitude -s"
Sep 24 00:34:10 qaa earlyoom[1260]: kill_release: pid=848416: process_mrelease pidfd=4 failed: Invalid argument
Sep 24 00:34:11 qaa earlyoom[1260]: process 848416 exited after 0.701 seconds
