Imaging error: Overflow

[Michael Perata]

While running an AcquireImages plan last night I received an "Imaging error: Overflow" during the second exposure. The first exposure was successful although without guiding.

Here is a snippet of the plan (full plan text attached):

**Autoguiding failed.
**Guiding failed, continuing unguided. Will try again next image.
Imaging to M48-S001-R001-C001-RED
(taking 300 sec. exposure, RED filter, binning = 1)
(unguided dither, doing small slew)
Start slew to dither...
**Imaging error: Overflow
(turning tracking off for safety

At the time, I also received a MaxIM DL error message:

"MaxIM DL failed to start the slew. The telescope driver
reported the error: "

The MaxIM message was persistent, BUT, the guider continued to guide during this message as evidenced by the Guiding Graph.

Any ideas where to look?
