![]() APAR status Closed as program error. Error description SIGSEGV (ABEND0C4) at offset 08C6 in ORB_Request::read_asynch_message(ORB_Request::ORBR_ReturnArea&, AsynchData*,SessionHandle*,G suddenly. the ABEND0C4 occured because the callers R3+0 is null. The SessionHandle passed to read_asynch_message() has a pointer to the Session at offset +0, and in this case the value of the pointer is 0x00000000. It should not be zeros.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4/ABENDS0C4 in ORB_Request:: * * read_asynch_message at offset x'08C6'. * **************************************************************** * RECOMMENDATION: * **************************************************************** The Session address contained in the SessionHandle passed to read_asynch_message was 0. The storage for this SessionHandle is contained within the AsyncData area within the Session Object storage. Cleanup code from a prior use of this Session object had cleared the Session pointer component of the Session objects' SessionHandle after it was made available for reuse. Before this clearing occurred the Session Object was allocated and initialized to a new connection. The later clearing of the Session pointer within the SessionHandle corrupted the Session and caused the ABEND0C4.Problem conclusion Code has been modified to eliminate the clearing of the Session pointer within the SessionHandle after the Session has been made available for reuse. APAR PK22560 1s associated with SERVICE LEVEL W502040 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
