Unexpected 'ps_aux' output.

[lonicerae]

Hi Richard,

When I was using 'redhat-access-insights', it seems that the collected data 'ps_aux' is not the result as it should be. Please kindly check the follows:

$ cat ./test-host1-20161207134651/insights_commands/ps_aux | wc -l
3
$ cat ./test-host1-20161207134651/insights_commands/ps_auxcww | wc -l
287
$ cat ./test-host2-20161207134705/insights_commands/ps_aux | wc -l

$ cat ./test-host2-20161207134705/insights_commands/ps_auxcww | wc -l

I can confirm this bug in my local system:

[myhost-20161208161424]# cat ./insights_commands/ps_auxcww | wc -l
205
[myhost-20161208161424]# cat ./insights_commands/ps_aux | wc -l
1

[myhost-20161208161424]# cat ./insights_commands/ps_aux

[myhost-20161208161424]# rpm -q redhat-access-insights
redhat-access-insights-1.0.11-0.el7.noarch

Can you please help to look into this issue? Thanks!

@chenlizhong Has this issue been resolved via the shared mappers?

No problem now.
