Many thanks Florian. Error seems to be displayed when vmxnet3 is used.
If I use another one like e1000, warning is not displayed. Strange ...,

Strange kernel error when SL6.1 hosts starts
Hi all,
I have installed two SL6.1 (fully patched) hosts with cman+rgmanager
suite for HA services. When both nodes starts, this error is displayed:
NOHZ: local_softirq_pending 08
What does it means?? I have another pair of RHEL6.1 hosts with
cman+rgmanager and this error doesn't appears ...
All hosts are installed under ESXi 5.
Thanks
