    JBPM 5.4 on linux redhat kernel 2.6.32-131.0.15.el6.x86_64 can not open drools-guvnor

    Panupong Chantaklang Newbie

      My Step

      1. I install jbpm 5.4 from extract jbpm-5.4.0.Final-installer-full.zip to my developme machine
      2. run command ant install.demo.noeclipse
      3. run command ant start.demo.noeclipse


           Every things look well but when i try to connect http://mydevmachine:8080/drools-guvnor.

      i can access first page but system show error 500. After i saw server.log many line show erro like


      Caused by: java.sql.SQLException: Java exception: '/app/jbpm-installer/repository/workspaces/default/db/seg0/c3f1.dat (Too many open files): java.io.FileNotFoundException'.

      its mean derby cannot create data file.
