Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• System abend S402 running CICS BAC due to an error in module
  CBKCWCRS.
  If either CICS BAC File Maintenance Utility updates or CICS ISPF
  interface browse requests are performed at the same time as CPSM
  API requests, then CPSM API requests fail and CICS BAC hangs.
  
  The CBAC task program that handles "non-BRU requests" or
  requests not from the batch request utility  (i.e. requests from
  the file maintenance utility or either of the other two user
  admin facilities) wasn't providing the proper serialization.
  Looking further at system dumps, a system abend 402 is detected.
