  Steps taken:
  
  1. Start the Administrator client.
  2. Select the Configuration tab, then select Registration and
     Person.
  3. Complete all required fields, allowing the Adminp task to
     create the mail file in the background.
  4. The Adminp tasks failed indicating the file name targeted
     for creation already exists.
  5. A review of the NSD reveals the issue is similar to APAR
     LO01657.
  6. The remaining mail files are created during the server
     recovery/restart process.

Temporary fix

Comments

• This APAR is associated with SPR# DSAN8NUV5S.
  The reason of server  crash is that the multiple thread to
   share the same global variable hblacklist.  the each thread
   will allocate the memory and free the memory location.  but
   one thread may allocate to use it, the other thread try to
   free it.  That will cause the crash.  The fixed code is to
   move the hblacklist  to osinit just to allocate hblacklist
   once with function MailmiscPolicyApiInit() to use for all
   threads, when the process is done,  to free the memory at
   final with function MailmiscPolicyApiTerm().
