It looks like Houdini render process is returning a non-zero exit code. Edwin recommended to ignore this exit code if it renders fine outside Deadline. Here is a KBA article to troubleshoot Houdini render issue.
If it render fine outside following this documentation, you can follow Edwin’s recommendation on this forum thread: Houdini-Redshift exit code 134 workaround - #2 by eamsler
I hope this would help. Could you also be able to share the render log from the job which failed to investigate further.
