In the comments between you and hglkrijger in the gitub issue above,
it appears that the problem has been resolved, and the issue was closed
by hglkrijger on Sep 7.

If that's true, can you or Microsoft provide a patch?

Comment 3 Yuxin Sun 2016-09-12 02:09:55 UTC
Hi Dave,

It seems that we can resolve it ether by Microsoft's fix or by spec file. We are still waiting for the PM's final conclusion. If any progress I'll update here at once. Thanks!

Comment 4 Yuxin Sun 2016-10-28 09:47:49 UTC
Verify in RHEL-6.8 GA build, WALinuxAgent-2.2.0 scratch build. 
Need to verify in WALinuxAgent-2.2.0-1 package

Comment 5 Dave Anderson 2016-11-04 14:21:48 UTC
I presume that the rhel6 package should be rebuilt with the same two
patches that have been applied in WALinuxAgent-2.2.0-3.el7:

Comment 6 Yuxin Sun 2016-11-07 11:19:38 UTC
Yes I think these patches should also be used in el6. I tested install/uninstall/upgrade/downgrade of the WALinuxAgent-2.2.0-2.el6 package and the result is pass.
I'll do more test of this package tomorrow.

Comment 7 Yuxin Sun 2016-11-08 06:54:49 UTC
Verified in WALinuxAgent-2.2.0-2.el6 RHEL-6.8-20160414.0. 

Steps:
1. Prepare a VM(RHEL-6.8) with WALinuxAgent-2.0.16 installed, and service started.
2. Run "rpm -Uvh WALinuxAgent-2.2.0-2.el6.noarch.rpm".
4. Check waagent -deamon process. Run "ps aux|grep waagent"
root      1429  0.3  0.3 203608 11036 ?        S    14:51   0:00 python /usr/sbin/waagent -daemon
root      1664  3.3  0.3 365496 13308 ?        Sl   14:53   0:00 python -u /usr/sbin/waagent -run-exthandlers

There's only one daemon process.
