To avoid these potential problems, use the Create multipart features parameter to create single part features to split potentially larger multipart features into many smaller features. Problems may also occur if the dissolve output created a feature at the maximum size on one machine, and this output was moved to a machine with less available memory. Very large features may cause processing or display problems or have poor performance when drawn on a map or when edited. This is especially true when there is a small number of unique values in the Dissolve Field(s) parameter or when dissolving all features into a single feature. For example, if the SUM statistic is used on a field named POP, the output will have a field named SUM_POP.ĭissolve can create very large features in the output feature class. The statistic used to summarize attributes is added to the output feature class as a single field with the naming standard of statistic type + underscore + input field name. The attributes of the features that become aggregated by dissolve can be summarized or described using a variety of statistics.

Pro being 64bit should also help but it appears there may have been issues there as well.

When you see this type of output in ArcMap, please make sure to try the same process using Background 64bit ( ). Additionally, running the Dissolve tool a second time on output that was created this way may result in very slow performance for little to no gain and may cause an unexpected failure. The maximum size of any output feature is determined by the amount of available memory at run time therefore, output containing tiles is an indicator that dissolving any further with the available resources would cause an out-of-memory situation or result in a feature that is unusable. Running Dissolve on the output of a previous dissolve run will rarely reduce the number of features in the output when the original processing divided and processed the inputs using adaptive tiling.
