APAR Error Description / Circumvention
-----------------------------------------------
When an error is set to be filtered in Licensed Internal Code
(LIC) logging, a VLOGFILTER task starts to be created. During
the task creation, Performance Data Collector encountered an
error requiring a LIC log to be generated, and subsequently
filtered. Again, the filter requires a VLOGFILTER to exist.
Since the original VLOGFILTER task did not complete an attempt
is made to create new task which encounters the same error. This
series of events continues, meanwhile allocating Machine Pool
storage, until Machine Pool storage can no longer be allocated.
Many other critical functions, that rely on Machine Pool
storage, can no longer function. The system becomes
non-responsive at that point.
CORRECTION FOR APAR MA39877 :
-----------------------------
The Performance Data Collector (Pdc) is hooked in the
task/process create path. This is how Pdc adds tasks/processes
to PEX collections when they are created while a collection is
active. Pdc encountered an error attempting to add the
VLOGFILTER task a the collection. The LIC code is changed to
correct the error on the call to Pdc to add a task/process to a
collection.
