[jira] [Created] (CLOUDSTACK-8611) CS waits indefinitely for CheckS2SVpnConnectionsCommand to return

Likitha Shetty created CLOUDSTACK-8611:
------------------------------------------

             Summary: CS waits indefinitely for CheckS2SVpnConnectionsCommand to return
                 Key: CLOUDSTACK-8611
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8611
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
            Reporter: Likitha Shetty
            Assignee: Likitha Shetty
             Fix For: 4.6.0


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.
