Error description

  • Communications Server for Windows
    ---------------------------------
    A memory leak occurs in the TN3270 Server when using SSL and a
    tn3270 client does not complete the SSL negotiation (in this
    case, because it did not recognize the server's certificate).
    
    Visible symptoms are that the TN3270WN.EXE process memory usage
    slowly increases in size. Eventually, all client connections are
    lost and no new clients can connect. The windows system event
    log may record:
    TNS0024E  The system call (ERR_CREATETHREAD) returned an
    unexpected return code (12).
    

Local fix

  • Stop and restart Comunications Server.
    

Problem summary

  • USERS AFFECTED: All using TN3270 Server with SSL.
