Issue/Introduction

"+IEW2974T C008 REGION TOO SMALL TO ESTABLISH BINDER ENVIRONMENT"  
"+DFHSR0606 cicsname Abend (code 0F4/AKEB) has been detected"
  Occurs during SymDump for CICS dump capturing. 

Resolution

IEWBIND is used by SymDump for CICS and requires about 750K of "BELOW THE LINE" storage.To ensure there is sufficient below the line storage, make sure DSALIM is at least 750K less than PRIVATE AREA SIZE.
Some kind of z/OS tool such as SysView, Omegamon, or Mainview, will be able to determine the size of the private
area. DSALIM must be about 750K less than this.

Example:

If the CICS REGION size is 256M, and the EDSA size is 230M (26M left), decreasing EDSA to 180M could resolve the problem.
