We have recently upgraded zcs-4.5.3_GA_733.RHEL4 to zcs-4.5.5_GA_838.RHEL4 OpenSource edition on Centos4.4, previously had no problems.

After the upgrade ClamAv stopps working and I see
Code:
ClamAV-clamd: Can't connect to INET socket 127.0.0.1:3310: Connection refused
ClamAv appears to start normally, even when started zmclamdctl individually

Code:
zmcontrol start
Host zimbra
        Starting ldap...Done.
        Starting logger...Done.
        Starting mailbox...Done.
        Starting antispam...Done.
        Starting antivirus...Done.
        Starting snmp...Done.
        Starting spell...Done.
        Starting mta...Done.
but zmcontrol status shows otherwise:

Code:
zmcontrol status
Host zimbra
        antispam                Running
        antivirus               Stopped
                zmclamdctl is not running
        ldap                    Running
        logger                  Running
        mailbox                 Running
        mta                     Running
        snmp                    Running
        spell                   Running
when restarting the clamd log ends at
Code:
Tue May 15 20:50:28 2007 -> +++ Started at Tue May 15 20:50:28 2007
Tue May 15 20:50:29 2007 -> clamd daemon 0.90.2 (OS: linux-gnu, ARCH: i386, CPU: i686)
Tue May 15 20:50:29 2007 -> Log file size limited to 20971520 bytes.
Tue May 15 20:50:29 2007 -> Reading databases from /opt/zimbra/clamav/db
A server reboot seems to clear this and the ClamAV starts normally.
Hope someone can help.
Thanks in Advance.
