Hello,
Not sure why you are running the system with trace level 2.
It is very rare to need level 2 trace information.
Anyway, the dev_disp reveals that the work processes are dying.
The dev_w0 shows the following error:

What is the value of the parameter "abap/buffersize"?
If it is not set, try setting it to 200MB (200000).
You might also want to reboot the server in order to clear the shared memory.
Best regards,
