Error description

  • You are using HTTP connection pooling with outbound SSL
    connections and are experiencing a storage creep (outside DSA
    storage) issue.
    .
    In the VSMDATA, there is a build up of x5000 byte pieces of
    storage in subpool 2 with key 8 that contain HANC and GSKSOC
    eyecatchers.
    .
    Further diagnosis found that
    when an outbound SSL socket is created via a URIMAP and that
    URIMAP has a SOCKETCLOSE value set, so that the outbound
    connection pooling is used, then when the socket gets timed out
    the gsk_secure_socket_close call is not being issued.
    
    .

    *                      storage is experienced when HTTP        *
    *                      connection pooling is being used        *
    *                      with outbound SSL connections.          *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When an outbound SSL socket is created via a URIMAP and that
    URIMAP has a SOCKETCLOSE value set, outbound connection pooling
    is used.  However when the SOCKETCLOSE value times out only a
    close() call is issued for the socket.
    No gsk_secure_socket_close() call is issued and so the GSKSOC
    control block is not freed which results in a storage leak.
    

Problem conclusion

  • DFHSOPL has been changed to issue a gsk_secure_socket_close when
    closing a pooled connection socket that is using SSL.
