Doc Text:	The hypervkvpd daemon did not close the file descriptors for pool files when they were updated. This could eventually lead to hypervkvpd crashing with a "KVP: Failed to open file, pool: 1" error after consuming all available file descriptors. With this update, the file descriptors are closed, correcting this issue.

Description Libor Miksik 2013-04-18 06:31:34 EDT

This bug has been copied from bug #949664 and has been proposed
to be backported to 5.9 z-stream (EUS).

Comment 9 Bian Jinwei 2013-04-24 06:01:01 EDT

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.
