> CS waits indefinitely for CheckS2SVpnConnectionsCommand to return

> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Reporter: Likitha Shetty
> Assignee: Suresh Kumar Anaparti
> Fix For: 4.9.0
>
>
> On one instance, CS began to execute CheckS2SVpnConnectionsCommand command on
> a router but the command result was never returned to the MS. If a command
> never returns, then 'DirectAgent' thread executing this command is blocked
> indefinitely and cannot pick up any other request.
> Now since this command is designed to execute in sequence on a host and is
> run regularly, every execution of that command thereafter on that particular
> host ended up picking up a DirectAgent thread and waiting for the previous
> execution to complete. And hence overtime, the host ended up using and
> blocking all 'DirectAgent' threads indefinitely.
