I agree that my configuration was wrong , but if a critical aux shortage
occurs, and it is a Unix process, how can you kill, delete it ?

I would respectfully submit that the application did not bring down the system. It was a system configuration issue.

Hi
I see , my point here, how a normal, nonauthorised application can
brings down the system.

In our systems (till now) we set the MEMLIMIT to NOLIMIT, we have 6G

A test 64 bit unautorised application tried to alloc and set a 4Gbyte
storage, it led to an IPL wit critical aux storage shortage.
I was unable to kill the process.
Now we set the MEMLIMIT to 2G.
Any way to prevent his ?
The same way you would have limited 24-bit or 31-bit allocations.
The IEFUSI SMF exit. Search the archives for more information.
I forgot to mention: You should also beef up your aux storage. If you
have 6G real, you should have enough aux storage to support
*much* more virtual storage usage. See the INIT and tuning guide and
reference for details on how to estimate the size.
