slow virus scanning with clam, amavisd-new and postfix

Hey
I've been running this setup for several years, and haven't had any problems
so far... But after upgrading to v. clamav-0.90.3-1.el4.rf scanning emails
for virus is taking 50-60 seconds per email... :-(
By searching the net, I found out that it's because I've been using clamav
as a backup email scanner in amavisd-new, and I should use the deamon, as
primary virus scanner, but enabling these lines i amavisd.conf only gives an
error in my log, and the mail is still beeing scanned by my backup
emailscanner... (clamc)
I've enabled these lines i amavisd.conf
['ClamAV-clamd',
\&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd.pid"],
qr/\bOK$/, qr/\bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],
And get this error in the logfile:
(!)ClamAV-clamd: Can't connect to UNIX socket /var/run/clamav/clamd.pid:
Connection refused, retrying (2)
(!)run_av (ClamAV-clamd, built-in i/f): Too many retries to talk to
/var/run/clamav/clamd.pid (Can't connect to UNIX socket
/var/run/clamav/clamd.pid: Connection refused) at (eval 57) line 310.
The pid file is there, and are owned by the clamav user, and the amavis user
is a member of the clamav group, and file permissions on clamav folder with
the pid file is 755, I've also tried 775 but with no change.
Clamd is running:
service clamd status
clamd (pid 10793) is running...
Anyone has an idea how to fix this ? :-)
software versions:
CentOS 4.5
postfix-2.2.10-1.1.el4
amavisd-new-2.5.1-1.el4.rf
clamav-db-0.90.3-1.el4.rf
clamd-0.90.3-1.el4.rf
clamav-0.90.3-1.el4.rf
Thanks in advance.
Best regards
jacob
