@kisnalam

1. Which scanner version do you use? line number does not match.
2. How many files in your directory? Find last visit directory using --trace option. If there are too many files in one directory, java heap can be exhausted. If you have sufficient free memory, use -Xmx4G switch to allocate 4GB at maximum.
3. Which java version do you use on AIX? java -version

Also see #123 (comment)
It may help if you have millions of files in a directory.

@kisnalam OutOfMemoryError issue is resolved in v2.9.0. Would you test it?
