The following processes are exhibiting a $RECEIVE queue length that
may indicate an application/application-configuration problem:
0,433 $X0BS6 $SYSTEM SYS02 LOGIN 0.00% MSG/s: 0 Q-LEN: 1.91
0,514 $X0BTA $SYSTEM SYS02 LOGIN 0.00% MSG/s: 0 Q-LEN: 1.84
0,694 $X0BSP $SYSTEM SYS02 LOGIN 0.00% MSG/s: 0 Q-LEN: 1.92
0,743 $X0BST $SYSTEM SYS02 LOGIN 0.00% MSG/s: 0 Q-LEN: 1.69
Process Move Recommendations
This section of the report (Example 3-14) contains recommendations, based on the
GPA analysis of the node, for improving the performance of the system. It tells what
processes could be moved to other CPUs on the node to achieve a more balanced
load distribution and better utilization of existing memory. You implement the moves
that are appropriate for your particular situation.
Example 3-14. Process Move Recommendations

As Example 3-14 shows, the report gives: (1) the identification number of each
memory-short or overutilized CPU and (2) the number of pages of memory shortage
or, in the case of an overutilized CPU, the percentage of overutilization (before any
process moves but after the GPA primary path moves for the CPU).
(1)
CPU: The identification number of each memory-short or overutilized
CPU.
(2)
SHORT MEMORY BY: The number of pages of memory shortage
or, in the case of an overutilized CPU, the percentage of
overutilization (before any process moves but after the GPA primary
path moves for the CPU).
For each processor, the report lists:
(3)
The process identification (CPU number, PIN, and process name).
(4)
The program file (volume, subvolume, and filename).
