Resolution

AL2QXFVB and AL2QSVFB are both jobs that executes the BPXBATCH program to start and stop the X-Server application, via IBM supplied scripts. The X-Server (XVFB) is a part of IBM Ported Tools.

In order to debug XVFB failures or problems, IBM support needs to be engaged, as it is not a Broadcom tool.
