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

Description

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
size.

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

debug-level guru
debug-all

log-file /var/tmp/scd.log

Let us know the content of the file, when you see the problem.
