Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• EZBRERIN is the Resolver's res_init() routine.  Some
  multi-tasking applications that invoke LE programs from within a
  task can get ABENDS00C4 in the first resolver call (such as
  gethostbyname()) from that program.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the IBM Communications Server   *
  *                 for z/OS Version 1 Release 13 IP : Resolver  *
  ****************************************************************
  * PROBLEM DESCRIPTION: Resolver abends using an old pointer    *
  *                      to Language Environment information.    *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF                                *
  ****************************************************************
  A single-threaded, POSIX(OFF) Language Environment
  application runs in a nested environment and issues multiple
  resolver API calls. Through some sequence of calls or task
  termination steps, Language Environment provides a pointer to
  information used by resolver that is different from the
  previous pointer used by this resolver task, but the resolver
  uses its old saved pointer and accesses freed storage,
  resulting in the abend.

Problem conclusion

• The resolver will save and use the input pointer provided by
  LE on this API call.
