Description

Not sure if this one has been logged.

I have seen the following chats which describe this behaviour, but it's hard to reliably replicate. It seems to be a race condition or a timeout being hit on starting a camel context:

http://camel.465427.n5.nabble.com/Upgrade-Camel-2-10-1-2-11-0-Camel-keeps-restarting-td5731854.html

Basically the steps to replicate are:

• Deploy a blueprint.xml file to the karaf deploy directory, which has the following:

  <cm:property-placeholder persistent-id="user.example" update-strategy="reload" />
  

• Notice that karaf will continuously reload the camel blueprint.
