Here are some errors that one might face when running experiments using Saul:

##java.lang.OutOfMemoryError: GC overhead limit exceeded Thanks to https://github.com/crockpotveggies/tinderbox/wiki/Common-Errors, here is the solution:
Sometimes the .sbt_config file isn't set when it is installed OR the defaults just aren't enough. Try the following options one-at-a-time in order to resolve the problem:

1. Add the following line to the ~/.bash_profile in OSX or Linux: export _JAVA_OPTIONS="-XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -Xms1024m -Xmx2G -Xss256m -XX:MaxPermSize=4G"
2. (Mac OSX) Create a file at ~/.sbt_config and paste the contents: SBT_OPTS="-XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -Xms1024m -Xmx2G -Xss256m -XX:MaxPermSize=4G"
3. Start up SBT using the command sbt -mem 4000 run
