What starts and stops cloudscape? Perhaps it is never shut down properly. For instance, we go to some trouble to shut down hypersonic on jboss shutdown.
Embedded Cloudscape db is started by JBoss no? We put the cloudscape.jar file in /jboss/lib/ext and modify the jboss.jcml file in /conf/tomcat (we use run_with_tomcat.bat to start JBoss) to use the cloudscape datasource in jboss/db/cloudscape. Its really weird because this problem doesn't occur in Windows OS. Only solaris/linux. Maybe I should talk to the folks at informix.
