socket dissapears, how to t/s ?

I have a new Centos Postfix/Amavis server, it came as a preconfigured
iRedMail server, a pre configured Postfix + ancillaries

amavisd-new was installed and running, but, after a few days, amavisd
started crashing

I suspect a yum update of clamd from 'incompatible repos' caused it (?)

I'm trying to figure out what's going on, when I start 'clamd' I get a
socket as so:

# service clamd start
Starting Clam AntiVirus Daemon:                            [  OK  ]

# ls -al /var/spool/amavisd/clamd.sock
srw-rw-rw- 1 amavis amavis 0 Dec 16 10:29 /var/spool/amavisd/clamd.sock

but, when I start amavisd it fails with

# amavisd debug
...//...
Use of uninitialized value in subroutine entry at
/usr/local/share/perl5/Net/Server/Proto.pm line 125.
Dec 16 10:31:26.427 emu.sbt.net.au /usr/sbin/amavisd[10618]: Net::Server:

and, the socket disapears ?

# ls -al /var/spool/amavisd/clamd.sock
ls: cannot access /var/spool/amavisd/clamd.sock: No such file or directory
# service clamd status
clamd (pid 9263) is running...

any suggestion how to figure this out?
