We are using Continua to run our Finalbuilder build scripts. These have a number of async action groups to build things in parallel.
That makes it hard to find errors in the build however as Continua does not display these logs in a useful manner. Instead it keeps adding the async actions as a child of the previous action which makes the entire log disorganized and it keeps running to the right until the entries can not be displayed anymore.
Unfortunately the fix for this will have to wait for FB8, there is a mismatch between how the logging was designed in Continua and how it works in FinalBuilder (misscommunication between developers). Our plan is to re-implement the logging in FB8 as part some other improvements we are working on.
A work around you can try is to export the log from the finalbuilder to the build workspace, add a workspace rule to copy the log back to the server, and configure the logfile as a Report in Continua CI - http://wiki.finalbuilder.com/x/agMZ
