------------------------------------------
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.
