[Postfix-es] Problema con Clamav: Can't connect to UNIX socket /var/run/clamav/clamd.ctl:

[Alejandro Facultad]

Buen dia nuevamente, tengo 
Debian+Postfix+Amavisd.new+Spamassassin+Clamav, pero my sistema esta 
sobrecargado porque el clamav esta usando el 100% de CPU.
Estos son los datos:

/var/log/mail.log:
(host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, 
id=03063-01, virus_scan FAILED: virus_scan: ALL VIRUS SCANNERS FAILED: 
ClamAV-clamd av-scanner FAILED: Too many retries to talk to 
/var/run/clamav/clamd.ctl (Can't connect to UNIX socket

268.; ClamAV-clamscan av-scanner FAILED: /usr/bin/clamscan timed out at 
(eval 44) line 462. (in reply to end of DATA command))

ls -l /var/run
cdrwxr-xr-x 2 clamav clamav  144 2008-02-22 11:58 clamav

ls -l /var/run/clamav
srwxrwxrwx 1 clamav clamav 0 2008-02-22 11:58 clamd.ctl
-rw-rw---- 1 clamav clamav 4 2008-02-22 11:58 clamd.pid
-rw-rw---- 1 clamav clamav 4 2008-02-22 11:39 freshclam.pid

htop:
clamd usa 100% CPU

/etc/group:
amavis:x:108:clamav  (el usuario clamav pertenece al grupo amavis)

Que puedo hacer ???

Muchisimas gracias

Alejandro
