[chef-dev] Application Cookbook Memory Leaks (was Re: 7/22 Opscode Code Review)

[Lamont Granquist < >]

Just wanted to raise the visibility of COOK-3360.  This was a bug that 
was causing an entire run_context to leak every time chef-client 
converged when running daemonized, and rapidly would lead to chef 
consuming >>1GB of RAM and beyond.  It should affect everyone using the 
2.x application cookbook.  A version bump was made to 3.x for the 
application cookbook since all the other application_* cookbooks needed 
to be updated for an API change.  The syntax for users should not have 
changed at all from 2.x -> 3.x (and a major version bump was not done on 
the application_ruby, etc cookbooks).

Chef 11.6.0 has also switched the default so that the process which is 
daemonized is thin and forks off a process that does all the work of 
converging the node which should mitigate similar memory leaks in the 
future.
