Is it the chain from the timer to the timeout node?  Why would a chain ever successfully originate from a timer event?  It's not a user hoping to not get dropped.

Do you mean, you are using the process variables in the parent rule using fv!processInfo ? If not, then you don't need chaining because the sub-process runs synchronously.
