The tool works, but I get warning 000632: Datum conflict between map and output, and the output is divided. I have checked to see that output is set to match input. I don't know what's wrong. Help appreciated. Thanks!
Take a look at this:
000632: Datum conflict between map and output.—Help | ArcGIS for Desktop
The 'solution' is:
This is a warning; no change is necessary. If the warning is unexpected, check the current setting of the output coordinate system environment. The default setting is set to Same as Input.
You can Google the warnings. This one is at 000632: Datum conflict between map and output.—Help | ArcGIS for Desktop .
It means your data frame is in a different coordinate system than your original data and is being projected on the fly. It is only a warning, so you can either ignore it or change the data frame to match the feature class.
Part of this may be due to your system is having memory issues in relation to the task at hand. From the ESRI Help:
The availability of physical memory may limit the amount (and complexity) of input features that can be processed and dissolved into a single output feature. This limitation could cause an error to occur, as the dissolve process may require more memory than is available. To prevent this, Dissolve may divide and process the input features using an adaptive tiling algorithm. To determine the features that have been tiled, run the Frequency tool on the result of this tool, specifying the same fields used in the dissolve process for the Frequency Field(s) parameter. Any record with a frequency value of 2 has been tiled. Tile boundaries are preserved in the output features to prevent the creation of features that are too large to be used by ArcGIS.

The above probably explains the "output is divided" message. While this does not directly explain the Datum message, it may be contributing to the problem.
