Hello,
I apologize for not posting directly to the archived forum but it appears that the option to enter new posts is disabled.
Thank you for your continued support of Maker and your responses to the forum posts. I have been running Maker (V3.01.02) to annotate a apple genome that consists of 17 chromosome-length scaffolds and some small contigs.
In my various tests in running Maker, the vast majority of the smaller contigs were annotated failed. I'm not sure the long scaffolds finished rather than smaller contigs.

The work in run.log.child.0 is FINISHED. While in the theVoid.scaffold1A/run.log.child.1, the error code showed below:
```

My command is "mpiexec -n 8 /data/liuyu/Software/maker/bin/maker -base CF_hap1_part3_test part3_round1_maker_opts.ctl maker_bopts.ctl maker_exe.ctl". The mpiexec is used by MPICH(v3.3.2). And When I test and use the MPICH2, the error is same. Meanwhile, when I use less number of processes, the task is failed too.
Thanks for any troubleshooting tips you can offer.
Best wishes,
Yu Liu
