Issue happens as there are more than one thread processing connect for a host simultaneously. The VM full sync. is not designed to work in this scenario and as a result user VMs may get stopped incorrectly. Direct agent scan task runs at regular intervals (direct.agent.scan.interval defaulted to 90 secs) and identifies hosts that needs to be processed for connect. In a normal scenario hosts mostly get connected within that interval and there are no issues. But if due to some reason the connect process takes more time and is not completed by the time next agent scan runs. In this case, based on the db. state same hosts may get picked up again. And then there will be situations where more than one thread is processing connect for the same host. The fix is to check if there is a thread already processing connect for a host and in this case all subsequent threads for that host will simply bail out. Also there may be a scenario where one thread already completed processing connect but another thread already got scheduled before that and will again repeat the same. This is also prevented by putting appropriate checks. |

Apache CloudStack Version 4.2.0
About Apache CloudStack
Apache CloudStack is software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering.
Apache CloudStack currently supports the most popular hypervisors: VMware, Oracle VM, KVM, XenServer and Xen Cloud Platform. CloudStack also offers bare metal management of servers, using PXE to provision OS images and IPMI to manage the server. Apache CloudStack offers three methods for managing cloud computing environments: an easy to use Web interface, command line tools, and a full-featured RESTful API.

Notice of Cryptographic Software
This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.
The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.
The following provides more details on the included cryptographic software:
CloudStack makes use of JaSypt cryptographic libraries
CloudStack has a system requirement of MySQL, and uses native database encryption functionality.
CloudStack makes use of the Bouncy Castle general-purpose encryption library.
CloudStack can optionally interacts with and controls OpenSwan-based VPNs.
CloudStack has a dependency on Apache WSS4J as part of the AWSAPI implementation.
CloudStack has a dependency on and makes use of JSch - a java SSH2 implementation.
