[horde] Horde logging not working.

[gwen]

I realize I'm probably missing something basic here, but I'm just not
seeing it.  Horde stopped logging on Dec 08, and hasn't started back
up.  I have need for it to log now, so I really need to get this
working again.

The partition the logs are on have plenty of space left (13G), the
file is as follows:

-rw-r----- 1 apache root 233147 Dec  8 18:49 /var/log/horde.log

I have the log configuration in conf.php excerpted here:

$conf['log']['priority'] = 'PEAR_LOG_DEBUG';
$conf['log']['ident'] = 'HORDE';
$conf['log']['params'] = array();
$conf['log']['name'] = '/var/log/horde.log';
$conf['log']['params']['append'] = true;
$conf['log']['type'] = 'file';
$conf['log']['enabled'] = true;
$conf['log_accesskeys'] = false;

Can anyone see what I am missing here?
