    Description

      While starting hawkular-1.0.0.Alpha3, getting below error in cosole:

      ERROR [org.apache.cassandra.service.CassandraDaemon] (ServerService Thread Pool – 73) Exception encountered during startup: java.lang.OutOfMemoryError: unable to create new native thread

      Checked the default max user processes on the environment.
      $ ulimit -u
      1024

      If the 'max user processes' are increased then the OutOfMemoryError is not visible (It worked for me when i increased to 3000 )
