Package: apt-cacher-ng
Version: 3.5-3
Severity: important

Running apt-cacher-ng to serve an sbuild container which gets used
heavily, I frequently get a hang in the daily cron job.  The process
tree involved is:

anacron -d -q -s
  └─sh -c run-parts --report /etc/cron.daily
      └─run-parts --report /etc/cron.daily
          └─apt-cacher-ng /etc/cron.daily/apt-cacher-ng
              └─acngtool maint -c /etc/apt-cacher-ng
SocketPath=/var/run/apt-cacher-ng/socket

This then prevents the system from reaching other /etc/cron.daily entries.

Oh crap. If it's still hanging at the time when you reach the console,
please make some analysis, like:

lsof > openfiles.txt
gcore -o acng.dmp $(pidof apt-cacher-ng)

and then compress them and send them directly to me.

Latest contents of /var/log/apt-cacher-ng/... would also be interesting.

Thanks,
Eduard.

Hallo,

Yes. This can be solved by checking for updated resolv.conf at certain
moments, for example when a new client connects. However getting the
replacement resolver in place is non-trivial because of the shutdown
situation.

You can grab a copy from
https://www.unix-ag.uni-kl.de/~bloch/acng/snap3.6.1/ if you wish, or
build from git, or wait a couple of days because I just found an
occurrence of #977611 which needs further investigation.

Best regards,
Eduard.
