54456 SSL library does not forward PEER CLOSE event to user application.
As a consequence, SSL resources are not released (even when forcing closure with wip_SSLClose()).
Subsequent SSL socket opening could fail with backtrace "ADL get memory" leading to a reset.

Data corruption is possible in first data exchanged between client and server using SSL channel Security 1.02
44486 If you are using an SSL socket and if an event WIP_CEV_ERROR is generated, the memory resources used by the SSL socket are not released even if a wip_close() is called.
If there is not enough available memory, the trace "ADL Get memory error" and RESET is sent, when a try to open another SSL session is made. To avoid the RESET, use the adl_errSubscribe function to trap the error (however a reset is necessary to reopen an SSL session).
