MEMGET ERROR (ALGET) Invalid index into memory channel: -1 (MEM_Get)

Error Message

The following error occurs while running ARC CLEAN or BUILD:

"Assembling polygons...
Invalid index into memory channel: -1 (MEM_Get)
FATAL ERROR
MEMGET ERROR (ALGET)
Bailing out of BUILD"

Cause

Incorrect information is sometimes written to the coverage mask file, msk or msk.adf, when polygon features are edited.

Solution or Workaround

• Delete the mask file.
  
  1. Use the ARC's COPY command to make a copy of the original coverage.
  2. Delete the copied coverage's mask file.

  Note: On UNIX, use ls to list the files under the coverage
  directory and rm to delete the msk.adf.
  
  
  3. Use ARC CLEAN or BUILD to process the copied coverage.
  Deleting the mask file causes the ARC BUILD and CLEAN commands to do a full build or clean rather than attempting to use a faster but more complicated partial build method.
• Use ARCEDIT BUILD or CLEAN if the coverage contains polygons.
  
  

  Note:
  The ARCEDIT BUILD and CLEAN commands do not use the mask file.
