[Avcheck] Code 15

[Fridtjof Busse]

Hi Michael
This seems to be a new one:
Nov 25 10:05:50 merlin postfix/pipe[2001]: 0D1E7234D0:
to=<fridtjof.busse@gmx.de>, relay=avcheck, delay=0, status=deferred
(temporary failure. Command output: avcheck: uexpected AVP return code
15 (0x013f) )

/var/spool/avp/dev/{console,null}exists (also /var/spool/avp/proc) and
permissions are correct.
Happens only if an infected email passes the scanner.
Ideas?
(Yes, I know I'm a big source of errors-messages ;))
Regards
Fridtjof
