amavis.conf  (we don't use debian so I have no idea how or what defaults 
'they' set in their package)

$enable_dkim_verification = 0

$enable_dkim_signing = 0

(I also have $sa_mail_body_size_limit = 600*1024 without any issues)

spamassasin

comment out (its my init.pre but search all *.pre files)

"loadplugin Mail::SpamAssassin::Plugin::DKIM"

But I think OP has bigger problems, I use the two above settings in 
amavis, but allow the plugin loading and its never caused differences.

Perhaps there are multiple signings and one fails whilst the rest don't, 
this will pass DMARC too, kind of like Thomas' posts to this list.
