The holdup for this has been due to a > semaphore lock around the code that allocates a machine for a reservation. > Without the semaphore, two people hitting the site at (nearly) the exact same > time can end up being assigned the same machine. > An idea I came up with to handle this is to only run the scheduling portion > of the code via the XML RPC API. A single web server would be elected as the > master. All web servers would call the scheduling part of the code via the > API on the master, allowing the semaphore lock to still function. If the > master server goes down, an election process would determine the new master. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
