Error description
After installation of RSU1403 an exit running under the CHIN address space terminates with ABENDA78 RC10 indicating that a STORAGE RELEASE was requested against an ACEE that is already free. A follow on symptom was an ABEND0C4 in Top Secret module TSSMVS2 as it tries to reference the same ACEE (for RACROUTE DELETE).

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ Version 7 * * Release 0 Modification 1 and * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: A SVRCONN channel with SHARECNV>1 and * * Send or/and Receive exits configured * * can cause abends (0C4, 0C1, SA78) in * * the exit code. * * * * The message CSQX112E is issued and the * * channel connection is terminated. * **************************************************************** * RECOMMENDATION: * **************************************************************** After V710 PTF UK95417 for PM86902 or V701 PTF UI14520 for PI08162, if a SVRCONN channel is configured with SHARECNV>1 and send or/and receive exits, the channel will call the exits using the same ExitUserArea storage for all the channel conversations. This causes the observed abends because the exit expects a separate ExitUserArea for each conversation.
Problem conclusion
The CHIN code has been changed to call channel exits using a ExitUserArea allocated for each channel conversation. 010Y 100Y CSQXREXT CSQXRMAS CSQXRMRS CSQXRMSS
