I am getting the following error when I try to erase a set of data from a file within a gdb. Any idea on what to do? I have done repair geometry multiple times on the input/erase datasets. I have 16GB RAM and close to a TB of free space. The dataset is approx 1.6m records. Arcmap 10 sp3. BTW how do I see the size of a dataset within a gdb?

Executing (Erase): Erase D:\SCRATCH\Projects\106\data\7_Merge.gdb\mergeall_1 D:\SCRATCH\Projects\106\data\5b_ReclassVector.gdb\Lidar_d2b d:\SCRATCH\Projects\106\data\6_Erase.gdb\srtm_m10m_e "1 Meters" Start Time: Sat Oct 15 02:53:38 2011 Reading Features...

The basic reason for this seems to be just the size of the dataset.

See Issues with large datasets

There are some other workarounds, none of them bulletproof, suggested in Invalid Topology [Topoengine error] ArcGIS 10.1

Ah, the 999999 error. I agree, probably the size of the dataset. I've encountered that error a few times with complicated buffers. Not sure if it's memory related. I have gotten that error on a machine with 2gb ram, then tried it on a different one with 4gb and it's successful. 16gb ram? You're running 64bit?
