Properties and configuration options you are mentioning no longer apply to AS7.
that was vfs 2.x thing, that was part of jboss 5&6
So, what are the workarounds available?
Is scheduling a cron job that takes care of deleting the vfs files the only option?
I also see that it affects the number of open files as it shows up in lsof -p <<JBoss Process ID>>
Also, is there a JBoss setting for the regular log files (server.log, access logs)?
By default, JBoss does not truncate the logs by either disk space / time. It creates a new file though every day.
