lftools archive command gets trapped in infinite loop of directories, and the build timeout does not terminate the job

We have a slightly weird build script that creates a link from a subdirectory back to a parent directory. At the bitter end of the job, the "lftools archive .." command is invoked by logs-deploy.sh with this pattern:

**/*.log

I think the recursive descent goes into an endless loop. Is there a way to limit the depth of the recursion to make this job more robust?

Why doesn't the build-timeout (set to 20 hours in our case) stop the runaway log archive process?
