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.
    

Local fix

    * Apply the PTF                                                *
    ****************************************************************
    A single-threaded, POSIX(OFF) Language Environment (LE)
    application runs in a nested environment and issues multiple
    resolver API calls. Through some sequence of calls or task
    termination steps, LE 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.
