[ic] Immediate and massive problem - GPG failing across multiple sites

[Cameron G]

Hi everyone, I'm in a panic and I'm hoping someone can help me, I have no
idea what is going on. 

GPG is failing to encrypt the order across every site we're running on a
particular server. It worked *perfectly* well up until the machine got
rebooted (was testing that it'd come back up for an imminent server move).
This is the error log: 

(ip address) w38LUJ4W:(ip address) - [08/March/2005:04:45:13 +0000] catalog
/cgi-bin/catalog/process.html PGP hard failure, command th
at failed: gpg --batch --always-trust -e -a  -r  'AF818985'
>/var/lib/interchange/catalog/tmp/pgp.w38LUJ4W.16670.out 2>/var/lib/int
erchange/catalog/tmp/pgp.w38LUJ4W.16670.err


The temp file reads: 

gpg: fatal: //.gnupg: can't create directory: Permission denied
secmem usage: 0/0 bytes in 0/0 blocks of pool 0/32768


Ok, so, where the hell is it getting that path? Why is it trying to create a
directory? This is failing on more than one site, so it's clearly an issue
with GPG itself, but how can cleanly resetting a computer nuke this sort of
thing? I'm googling like mad to work out how all this fits together, but
right now, I'm in trouble. Anyone have a better idea about GPG that can help
shed some light on this for me?
