Perhaps I've found the answer to my question about queue size:

[quote:314eeub6]
Disk assisted queues are special in that they do not have any size limit.
The enqueue an unlimited amount of elements. To prevent running out of
space, disk and disk-assisted queues can be size-limited via the
“$<object>QueueMaxDiskSpace” configuration parameter.

... queue-size</a><!-- m -->

So it looks like I am not supposed to specify
[b:314eeub6]queue.size[/b:314eeub6] if using Disk-Assisted mode.  Instead,
when memory is exhausted, things start writing to disk until
[b:314eeub6]queue.maxDiskSpace[/b:314eeub6] is reached (or
[b:314eeub6]$<object>QueueMaxDiskSpace[/b:314eeub6] in traditional format).

I will comment out the [b:314eeub6]queue.size[/b:314eeub6] option - I
should max out my queue about 12 hours from now, so I'll know if it worked
by tomorrow.

Per the recommendation in the rsyslog log file, I'm also increasing
[b:314eeub6]queue.workerThreadMinimumMessage[/b:314eeub6] to
[b:314eeub6]5000[/b:314eeub6]:

queue.workerThreadMinimumMessage is set quite low at 100. You should only
set it below 10% (5000) if you have a good reason for this. [try <!-- m
