AWS Snowball GC overhead limit exceeded

Question

I'm trying to send 5TB of data to S3 through AWS' snowball service.

I've received the snowball, and have connected to it through the snowball client okay. However, when I call the snowball cp command to copy files from the local server onto the snowball I hit issues. The cp command starts out fine but quickly chokes, followed by an error:

in thread "nioEventLoopGroup-2-45" Exception in thread "nioEventLoopGroup-2-12" Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded

I'm connecting to the snowball on a linux machine and running the following command

bash snowball cp -r - f -l /path/to/the/archive/on/the/server s3://jobname/directory

Thanks in advance.

Answer 1

An intensive background Java program was interfering with the transfer. After the program finished the cp command started working without throwing errors.
