Error description
When running long running workloads, storage leaks are causing
the customer to run out of aux storage.  The storage leaks have
been identified to occur in clients (including Web Server) and
server regions.
.
Method PartnerVersion::toContext in part bbooejsb.h was leaking
the EncapIIOP ojbect (280 + 512)
Frequency: 1 per client request.  It is used on outbound
requests from the server region as well as client space
(including WebServer).
Size of Leaked area: 512 (EncapIIOP buffer) + 280 (data)
Process: Client (Webserver), Server Region
.
Method ClientIPSession::preview_msg in part bbocsess.cpp was
leaking an 8-byte area from string returned from internal sco
structure, Client_Timeout().
Frequency: Frequently when environment varaible CLIENT_TIMEOUT
is explicitly set.
Size of Leaked area: 8
Process: Comm spaces (Control Regions and Client)
.
Method ClientSSLSession::preview_msg, same as above but for SSL
protocol
.
Method comm_outbound_locate in part bboocomm.cpp was leaking
previously cached SessionSecurityArea.destinationName value.
It is taken from the Hostname portion of the IIOP portion of
the IOR tags OR a x'40' length area from the PCCR (local) tag
(starts with system name followed by PLEX name:
SY1      PLEX1  ...).
Frequency: outbound calls.
Size of Leaked area: x'40' if using local Comm (PCCR) or length
of hostnames in the IIOP Tag in IORs.
Process: Comm spaces (Control Regions and Client)
.
Method Current::init_acee in part bboscurr.cpp was leaking a
MVS::RACO structure.
Frequency: Potentially once per send request.
Size: 16 bytes
Process: Control Region
