APAR Error Description / Circumvention
-----------------------------------------------
System terminated with srcB6005121. Further analysis shows that
there were multiple disk connection and channel interface HW
errors at the time of the failure, and that the recovery code
path eventually resulted in a stack overflow.
Failing SRCs:
word 1: B6005121 srcB6005121
word 3: 0002000A src0002000A
word 4: 00100011 src00100011
Additional Keywords:

CORRECTION FOR APAR MA46787 :
-----------------------------
The failing behavior involved an alternating series of storage
network data transfer errors followed by storage device state
changes. The recovery handling of these alternating errors
resulted in an attempt to extend beyond the end of the allocated
stack space. A change will be made to handle this recovery
within the available stack space.
