Yes, it means I only have a single drive

Yes, I am syslogging to the same physical drive.

I'd be happy to add a second drive for syslog (and anything else anyone
wants to recommend), and even switch to scsi drives.

But, before I do this, I want to categorically know that this is my
problem. That I am IO bound with the single drive.

My server can go for days without backing up. On the days it backs up,
my stats show no additional incomming load, the total daily number of messages
stays about the same. On a day that it does back up, often it will catch up
and the backlog clears.
