gpg-agent spawning all-consuming scdaemon process
Closed, ResolvedPublic


I just added a rule in /.gnupg/gpg-agent.conf to disable scdaemon, but before I
did, I was routinely returning to my computer to find that gpg-agent had started
scdaemon (which I don't use), and that scdaemon had grown to over a gigabyte in

The system is an Arch Linux installation, up to date as of 2013-04-25, running off
a 32gb MicroSD card with no swap.

I can't find any relevant log entries - advice on what to attach for diagnosis
would be appreciated.

To be useful bug report, please specify version number of your program. Also,
please show us your configuration file (if any). Specifically, do you have

To diagnose, please create a file .gnupg/scdaemon.conf with something like:

debug-level guru

log-file /var/tmp/scd.log
