APAR status

• Closed as program error.

Error description

• z/OS 2.5
  Analysis of SVC dump shows ABENDEC6 RSN0BF20049 occurred in
  BPXPRSRB +1E7A because the Aiocb address was invalidly freed by
  the application.
  
  When the Aiocb is freed, it's freed by the application owner.
  
  If it's any help, ArqUAioExitPtr at 38F070F0 --> points to the
  following eyecatcher:
  | x4..BANANA18..}. |
  
  This eyecatcher is the exit we are supposed to be returning to.
  
  
  The "BANANA18" eyecatcher can be seen in the
  wlp/lib/native/zos/s390x/bbgzsafm module that is shipped in the
  embedded Liberty with z/OS Connect.
