      Description

      I noticed that my job had not started and when I checked the log I found this message:

      Spot instance id in provision: sir-5j9rvbkjMay 07, 2021 1:56:08 PM INFO hudson.plugins.ec2.EC2RetentionStrategy startStart requested for EC2 (engineering-aws) - FreeBSD-13-amd64 lite for small jobs that don't need much CPU or RAM (sir-5j9rvbkj)May 07, 2021 1:56:08 PM INFO hudson.plugins.ec2.EC2Cloud provisionSlaveTemplate{description='FreeBSD-13-amd64 lite for small jobs that don't need much CPU or RAM', labels='aws-amd64-lite'}.

      and in the EC2 console I saw it was continuing to spawn machine after machine.  Luckily I was developing the job so I was paying attention and able to change the description to not include a '/' and kill all of the machines before it went too far.
