Package: librrd2
Version: 1.2.15-0.1
Severity: important
Hello.
This version of librrd2 used with munin 1.2.5-1 generate a OOM
condition in the munin-graph process.
munin-graph is used in the cron job of the munin package.
This is 100% reproductible every time (every 5min) the cron job is triggered.
Reverting librrd2, rrdtools and librrds-perl to 1.2.11-0.6 fixed the issue.
"free" output just prior to the OOM:
