I think the best thing to do would be to write your own deserializer that can read the file and understand the format. The reason the deserializer is pluggable in Spooling Directory Source is exactly for this reason (in fact, stack traces were one of the use-cases discussed on the mailing list). Since this is pluggable, you can use any logic to figure out when an event is complete.

Based on the recommendations at Flume 1.3.1 documentation, we are planning with http://flume.apache.org/FlumeUserGuide.html#spooling-directory-source . I would like to have the exception stacktrace that gets printed in the log of each application be treated as a single event rather than have each line of the exception as an event. To address this, should a change in the application logging be done to ensure the exception is written out to a single line in the log file or have a custom SpoolingFileLineReader that reads lines and treat "\\n\\d\\d\\d\\d" as a new line for a event.
