After some recent testing, it looks like there is a server-side memory leak in the latest OrangeFS release. We have seen servers whose memory climbs without bound while the server daemon is running.
I have a test case that is fairly simple. There is one RHEL5.5 64bit server and a single matching client both built from the 2.8.4 release tarball; the server config is attached. Create a simple file - mine is described below - and run the attached bash script (create-delete-loop.bash) against it. Memory is continuously leaked as seen by the chart I also attached. I tested this with the server's TroveMethod set to directio and alt-aio, and it appears to leak memory at the same rate. The file my test is using was created by this command: for i in `seq 1 65536`; do echo -n "b" >> b.txt ; done Bart.
