This bug has been copied from bug #949664 and has been proposed to be backported to 5.9 z-stream (EUS).
I have test the rpm package with the patch, the result is: the patch worked well. Two issues about the file descriptor are back to normal like below: <1>When reboot the guest rhel5.9.z, the hypervkvpd service has no "pool_3" file descriptor leak <2>When running the guest rhel5.9.z with a long time, the hypervkvpd service file descriptor will keep steady and unchanged From the above results, and I changed the bug status from "on_qa" into "verified". The details about the env and package: Host: hyper-v 2008 r2 and hyper-v 2012 Guest:rhel5.9.z with kernel2.6.18-354.el5 Hypervkvpd:hypervkvpd-0-0.7.el5_9.3
(In reply to comment #9) > Guest:rhel5.9.z with kernel2.6.18-354.el5 Sorry for my mistake, the rhel5.9.z kernel should be kernel2.6.18-348.5.1.el5. And with the kernel, the patch also worked well.
