Issue #4762 has been updated by Erik Auerswald.
We have tried to evaluate puppet for use over a satellite link. This was our first try at using puppet at all, as such we set up a test environment using webrick. While it worked over LAN, puppet broke trying to use the satellite link. Increasing the timeout (as suggested e.g. in http://groups.google.com/group/puppet-users/browse_thread/thread/291d70aa73eb3ab5/a4b0907b452ef084#a4b0907b452ef084 and http://comments.gmane.org/gmane.comp.sysutils.puppet.user/29788) did fix this. We set the timeout to 5.1s since a single round trip takes about 1s using our satellite provider. Without increasing the default timeout quite a few people will never reach a stage where they would think about replacing webrick for scalability issues. ;-) ---------------------------------------- Bug #4762: Speed of light interfering with normal puppet operation https://projects.puppetlabs.com/issues/4762 Author: John Ferlito Status: Investigating Priority: High Assignee: Category: Doh! Target version: Affected Puppet version: 0.25.5 Keywords: speed of light in a vacuum Branch: Puppet::Network::HTTP::WEBrick doesn't wait long enough for the connection to establish In puppet/network/http/webrick.rb there is the following code @mutex.synchronize do raise "WEBrick server is already listening" if @listening @listening = true @thread = Thread.new { @server.start { |sock| raise "Client disconnected before connection could be established" unless IO.select([sock],nil,nil,0.1) sock.accept @server.run(sock) } } sleep 0.1 until @server.status == :Running end end The select only waits for 100ms. In my situation I have servers in US and puppet masters in Australia. 100ms is nowhere near long enough for the connection to establish Maybe 2-5 seconds would be more appropriate -- You have received this notification because you have either subscribed to it, or are involved in it.
