    Description

      I've set up Active MQ in production with a shared file system master/slave configuration (KahaDB). I've set everything up and mounted the EFS on both EC2 instances.

      When I check the disk free stats I get 8 exabytes for the shared file system: 

      $ df -h 
eu-west-1a.***.efs.eu-west-1.amazonaws.com:/  8.0E     0  8.0E   0% /mnt/efs

      Unfortunately, ActiveMQ cannot interpret this number (8 exabytes). This may be due to integer truncation.

      Here is a snippet of the log:

      Store limit is 102400 mb (current store usage is 0 mb). The data directory: /mnt/efs/kahadb only has -8796093022208 mb of usable space - resetting to maximum available disk space: -8796093022207 mb 
Store limit is -8796093022207 mb, whilst the max journal file size for the store is: 32 mb, the store will not accept any data when used.
