Memory leak / stuck proces cause AOS to consume all memory

Dear community,

I'm having a problem with an AX2012 R3 CU13 AOS which is specfically reserved for mobile device users. I get a notification that a mobile device users is stock logging in. When I open the work user sessions from the Warehouse Management menu the client crashes with an Out of memory exception.

Upon further analysis I found out that some records from the table WHSWorkUserSessions have a really large rowsize and I think this is caused by a corrupt XML path. I think the user login is looping and is continiously writing in the table, cause the AOS to take up all available memory¿?. In this situation the AOS takes up 58/60 GB memory and CPU peaks to 97% which significantly slows down the AOS. Normally the CPU-usage is around 0-5% and RAM-usage is around ~10GB.

The only way I figured out to solve this problem is to delete the whsworkusersession directly through an SQL statement. But after deleting the session the AOS doesn't release the RAM so I think it isn't ending the process. I need to restart the whole AOS for this to be solved, which is quite a pain because there are several mobile device users logged in during business hours.

Is there any way to view which background processes a specific AOS is running and am I able to end these without having to restart the whole AOS?

Thanks in advance.
