![]() APAR status Closed as program error. 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 RegionLocal fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: Storage leaks in the WebSphere * * Application Server V4.0.1 for z/OS and * * OS/390 product can cause customer * * installations to run out of auxiliary * * storage. * **************************************************************** * RECOMMENDATION: * **************************************************************** Storage leaks in the WebSphere Application Server V4.0.1 for z/OS and OS/390 product can cause customer installations to run out of auxiliary storage. WebSphere is leaking storage in various sizes in control region, server region and client spaces.Problem conclusion Reported storage leaks were fixed in the WebSphere Application Server V4.0.1 for z/OS and OS/390 product.
