eventlet.spawn_n is the same as eventlet.spawn, but it’s not possible to know how the function terminated (i.e. no return value or exceptions)[1]. If an exception is raised in the function, spawn_n prints a stack trace. The stack trace will not be written to the log file. It will be lost if we restart the daemon.
Maybe we need to replace spawn_n with spawn. If an exception is raised in the function, we can log it if needed. Any thoughts? related bug: https://bugs.launchpad.net/neutron/+bug/1254984 [1] http://eventlet.net/doc/basic_usage.html -- Cheers, Jian
