GlassfishESB filebc component causes too many open file handles

I have an Glassfish ESB based CASA app running in production system (Win 2k3) for sometime now. I have recently encountered a very strange file handles related issue. It so happened that I was unable to perform any file related operations from inside the prod server. My analysis lead me to using the tool called "OpenedFilesView" which listed all open 开发者_开发知识库file handles for any process. I saw that there were thousands of file handles open for .LCK files on a specified folder (on a file server). This is the folder (say FolderB) into which my casa app tries to copy files that are received from a different folder (say FolderA). I have used FILEBC component for this file move operation. Has anyone faced this/similar issue?

I am told that an upgrade to Glassfish ESB v 2.2 solves this issue. I am trying it now...
