1215:   error accessing XMS overlay cache

     Explanation:  This message indicates that an error has occurred
     while the Blinker overlay manager is accessing XMS for the storage
     and/or retrieval of overlays in the overlay cache.

     Action:  Disable the BLINKER CACHE XMS command in the link script
     file.  If this fixes the problem, it is possible that you have a TSR or
     device driver working in the background which is manipulating XMS
     directly in a non-standard manner.  Try removing all TSRs and device
     drivers from the system except for the XMS driver, and test if the
     problem still occurs.  If it does, contact Computer Associates technical
     support.
