Hi,
we use 4.8.1. We know that the javadoc advises against it. Like I wrote,
the deletion of old documents (that appear during an update) would be
done while closing the writer. Unfortunately we can't close the writer
and we chose the force merge as alternative with less afford. Could
forceMergeDeletes serve our purpose here?
I will take a look into it with lsof, but I'm pretty sure, the files
will be held by some javaprocess.
Jürgen.

Do you need to call forceMerge(1) at all? The javadoc, certainly for
recent versions of lucene, advises against it. What version of lucene
are you running?
It might be helpful to run lsof against the index directory
before/during/after the merge to see what files are coming or going,
or if there are any marked as deleted but still present. That would
imply that something, somewhere, was holding on to the files.

Hi,
because we have constant updates on our index, we can't really close the
index from time to time. Therefore we decided to trigger forceMerge when
the traffic is lowest, the clean up.
On our development laptops (Windows and Linux) it works as expected, but on
the real Servers we have some wired behaviour.
Scenario:
We create a fresh index and populate it. This results in an index with a
size of 2 GB. If we rigger forceMerge(1) and a commit() afterwards for this
index, the index grows over the next 10 minutes to 6 GB and does not shrink
back. During the whole process no reader is opened on the index.
If I try the same stunt with the same data on my Windows Laptop, it does
nothing at all and finishes after a few ms.
Any Ideas?
Technical details:
We use an MMapDirectory and the Server is a Debian7 Kernel 3.2 in a KVM. The
file system is Ext4.
Thx,
Jürgen Albert.
