Isilon: isi_gather_info stops responding gathering firmware information in 8.1.2

When issuing a isi_gather_info it stops at the following point: 

# isi_gather_info --esrs
Unlocking gather-status
Gather-status unlocked

Looking at the process's that are running off the main isi_gather_info we see that it stops responding at the following:

python /usr/bin/isi_hwtools/isi_firmware_status --cluster --dump 

Not applicable

To see why the gather is stopping responding, leave it running and open a new SSH session.
Look at ps -auxwwd using the following syntax: 

isi_for_array -s "ps auxwwd | grep -i gather -A2" | grep -v grep

The following output is shown:

root 31829 0.0 0.0 480224 38676 - S 3:24AM 0:09.35 |-- /usr/bin/python /usr/bin/isi_gather_info --esrs (python2.7) root 31835 0.0 0.0 408816 36924 - S 3:24AM 0:46.17 | `-- python /usr/bin/isi_hwtools/isi_firmware_status --cluster --dump (python2.7)

The indented `-- tells us that this is a child process of isi_gather_info above it.
It shows that isi_gather_info is working on the isi_firmware_status.  

If the child process is killed using the command below, it stops the firmware process. This allows gather to continue but without the firmware data.  

This command should be issued on the node that has the gather running, or use isi_for_array to run it on the affected node.

# pkill isi_firmware_status

gather shows an error:

# isi_gather_info --esrs
Unlocking gather-status
Gather-status unlocked
Error running "isi_firmware_status" 

There is a fix to the underlying isi_firmware_status starting in patch: [8.1.2.0_KGA-RUP_2020-04][Multiple Kernel/Reboot Required Fixes](April 2020)

Install the latest KGA RUP and see if the issue still persists.
