Second task fail - out of memory error

Hi, I use tranquillity to load data from kafka to druid.
My segment granularity is 5 minutes.
The first task runs fine, while the second task fails with this error:

**CliPeon - Error when starting up.  Failing. Unable to provision, see the following errors:
1) Error in custom provider, java.lang.OutOfMemoryError**

What is the problem? How can I fix it?
In attachment the complete log.
Thank you!!!
