This seems to be just a timeout of an analysis process. The reason why you don't reach 100% is a different one: the progress of unpacking is also not at 100%. This means that something got lost during unpacking. There was probably some unhandled exception during unpacking which resulted in 2 files being dropped from scheduling. Did you see any other exceptions in the log?

Also you are not using the latest FACT release version. I suggest that you either switch to 4.1.1 (which contains many bug fixes that 4.1 does not have) or the latest master version.

it stop 30mins

All the errors that you posted should be handled in this line, so it there are no errors outside of the plugin or the process_next_object function, this is not the reason why it will not finish. The cwe_checker can be very slow for large binaries, so it is generally advisable to only run it on manually selected files (and not the whole firmware). It could very well be that the analysis is still running after 90 minutes. If you see a blue turning cogwheel below the "current analyses" like this

then it is still running.

Incidentally, there seems to be a bug in the cwe_checker plugin that lets it use unlimited amounts of system memory (which may also be related to your problems). #1156 should fix this.
