IBM MQ is preventing WebSphere Application Server (WAS) to be started in reusables ASIDs

In our business operation, we need to take down the WAS servers to make the user application unavailable at night. These stops (and later restarts) of the WAS servers are consuming the ASIDs in the systems they run and demanding frequent IPLs. We tried to start WAS in reusable ASIDs (REUSEASID=YES in the start command), but it ABEND 0D3. We were told by IBM Support that CLIENT (TCP/IP) connections between WAS and MQ, instead of BINDINGS (cross-memory) mode, avoid this situation.

Our request for IBM is that MQ is coded to address the issue below to WebSphere MQ connectors in all versions.

"Bindings mode WebSphere MQ connectors do not work properly in reusable address spaces. If you activate reusable ASIDs on your z/OS operating system, ensure that servers that are running with Message Listener Ports, as opposed to activation specifications, do not have the REUSASID=YES option on the START commands" https://www.ibm.com/docs/en/was-zos/9.0.5?topic=zos-reusable-address-space

With this capability, we are free to recycle WAS without worrying about running out of ASIDs and having to IPL our systems, even if we use BINDINGS mode.

    In order to protect address space integrity, z/OS will not allow address spaces to be reusable if they make use of certain types of PCs, or if they connect to other address spaces which make use of those PCs. The MQ address spaces makes of use of these types of PCs as part of its core function so we can't implement this idea I am afraid.

    Some details on why this protection is necessary is here: https://www.ibm.com/docs/en/zos/2.1.0?topic=ra-coding-cross-memory-services-avoid-loss-asids-from-reuse

    As you say one option here is to use client mode connections to connect from WAS to MQ. Another option would be to stop the WAS applications over night but leave the WAS server running.
