Subject file open handles?
Date Tue, 26 Jan 2010 18:20:59 GMT
Hi There

I am sure if this is anything to worry about, but I thought I'd ask just 
in case.

We're trying to get a handle on our file handles, so to speak. When I 
type the following:

root@ubuntu:~# lsof | grep java

I get a whole bunch of Index files created by Lucene. Are these file 
handles still open even though the files are deleted?

We are worried about the system running out of file handles over a 
period of time since the number of open file handles
appear to be increasing due to Lucene.

Could somebody please illuminate.

Thanks

Jamie
