Re: [Linux-cluster] When corosync-1.4.1-3.el6 will be released for rhel6.x?

Please take your time to read how RHEL release process works, but
basically and shortly. Ya, it's called EUS (Z-stream), and primary
purpose is for really hard/security bugs. To be honest, 709758 may be
annoying bug, but it doesn't fit to Z-stream very well, especially
because it can be seen only in very special conditions/broken environments.

But problem described in 709758 appears in my enviroment: One RHEL6.1 kvm host with two, only two with single CPUs, rhel6.1 guests running RHCS ...

See this:

a) running top on a rhel6.1 guest:

top - 13:50:02 up  4:25,  4 users,  load average: 5.91, 5.99, 6.71
Tasks: 132 total,   5 running, 127 sleeping,   0 stopped,   0 zombie
Cpu(s): 96.7%us, 3.3%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

b) trying to stop rgmanager under rhel6.1 kvm guest, never stops:

[root rhelclunode01 tmp]# time service rgmanager stop

c) running top under rhel6.1 kvm host:

top - 13:52:00 up  4:32,  1 user,  load average: 1.00, 1.00, 0.93

Then, what could be the solution if not fix will be released until rhel6.2?? disable all rhcs services and don't install RHCS netither on virtual or physical enviroments??

 Thanks.
