Error description
The 0c4 ABEND occurs in load module CSQQCON2. An LE application has issued an MQCONN and the address of the CAA from the LE environment has been saved by CSQQCONN in the QLOA. The LE environment has then been destroyed and another LE environment has been created, but the connection to the queue-manager has persisted (i.e. no MQDISC). Another MQCONN has then been issued, which should return MQRC_ALREADY_CONNECTED. However, CSQQCON2 passes the CAA address from the first LE environment to CSQBLEF, which results in the 0C4 seen here. . Additional Symptom(s) Search Keyword(s): ABEND0C4 ABEND0E0 RC30 0E0-30RC 30

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: An IMS application using MQ-IMS adapter * * generates 0C4 abend in CSQBLEF during a * * MQCONN/MQCONNX call. * * * * Abends 0E0-30 and 01F-04 have also been * * observed as consequences of the 0C4 * * abend in CSQBLEF. * **************************************************************** * RECOMMENDATION: * **************************************************************** An IMS application invoking several routines that call MQCONN/MQCONNX without calling MQDISC, generate abend 0C4 in CSQBLEF when called from CSQQCON2 with an invalid CEECAA control block pointer due to LE environment being terminated or recreated between MQCONN/MQCONNX calls.
Problem conclusion
CSQQCONN has been changed to refresh LE environment parameters on the existing HCONN when a MQCONN/MQCONNX call returns MQRC_ALREADY_CONNECTED in case that the LE environment has been terminated or recreated between MQCONN/MQCONNX calls. 100Y CSQQCONN
