> Key: CLOUDSTACK-8952
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8952
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Components: Virtual Router
> Affects Versions: 4.6.0
> Reporter: Wilder Rodrigues
> Assignee: Wilder Rodrigues
> Priority: Critical
>
> In the CsRedundant.py we have a line doing:
> proc = CsProcess(['/usr/sbin/keepalived', '--vrrp'])
> However, the CsProcess cannot find a process with the string search "--vrrp", which makes it always return false and restart keepalived.
> Due to the restart, the routers start a race condition to become master, which makes network features unavailable.
