Explorer.exe与K120Q GRID vGPU的CPU使用率恒定

在带有NVIDIA K1 GPU(K120Q)的XenServer 6.5 SP1上运行的XenDesktop 7.6映像(Win7 32位)遇到一个问题,其中explorer.exe进程不断占用5-10%的CPU,并且该进程每2分钟暂停几分之一秒
几秒钟左右。
这会导致开始菜单和其他资源管理器功能显示为“滞后”,并且用户抱怨他们的会话速度很慢。
经过一段时间(通常1-2小时),Explorer恢复正常。
禁用NVIDIA显卡/驱动程序摆脱了问题,我可以通过Process Monitor / Explorer确认它与NVIDIA GPU有关。
我已经用procdump做了一些转储我很乐意分享,但是我自己也无法解读其他的东西。
我也尝试了多个版本的驱动程序 - 我们使用的当前版本是348.27。
如果我们直接登录到VDA的控制台(例如,在XenCenter中),则不会发生此问题。
只有通过Citrix Receiver从Wyse Xenith Pro 2和Windows桌面登录时才会发生这种情况。
任何人都可以确认他们自己的XenDesktop + K120Q设置是否在explorer.exe上显示相同的CPU使用率?

Our XenDesktop 7.6 image (Win7 32-bit) running on XenServer 6.5 SP1 with NVIDIA K1 GPU (K120Q) is experiencing an issue where explorer.exe process constantly occupies 5-10% CPU and the process hangs for a fraction of a second every 2 seconds or so. This causes the start menu and other explorer functions to appear to "lag" and users complain their session is slow. After some time (usually 1-2 hours), Explorer goes back to normal. Disabling the NVIDIA card/driver gets rid of the issue and I can confirm with Process Monitor/Explorer that it has something to do with the NVIDIA GPU. I've done some dumps with procdump I'm happy to share, but unable to decipher much else myself. I've tried multiple versions of the driver as well - the current one we use is 348.27.

The issue does not occur if we log directly in to the console of the VDA (for example, in XenCenter). It only happens when logging in via Citrix Receiver, from both Wyse Xenith Pro 2 and Windows desktops.


Can anyone confirm if their own XenDesktop + K120Q setup exhibits the same CPU usage on explorer.exe?

我们已经看到了类似的问题,它与系统托盘中的无损指示器相关联。
禁用无损指示符(通过删除.exe)似乎可以解决此问题。
我们不知道的是造成它的根本原因或触发条件。
看看无损指标过程,看看终止它时会发生什么。

We've seen a similar issue where it's linked to the lossless indicator in the system tray.

Disabling the lossless indicator (by removing the .exe) appears to resolve the issue. What we don'tyet know is the root cause or trigger condition to cause it.

Take a look at the lossless indicator process and see what happens when you terminate it.

继Citrix之后,他们告诉我们XD 7.6 FP3中修复了一些问题 - 如果使用XD7.6,可能需要在http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-中查看这个问题。
6 / X-AD-什么新/功能包 -  3  -  VDA-的桌面操作系统---固定issues.html
特别是Jason指出的无损指标问题可能是:
在启用了HDX 3D Pro的VDA上,无损指示器任务栏图标(对于LLIndicator.exe)可能无法指示无损状态,并且在右键单击时可能不响应。
[#LC2931]
VDA 7.6.300与7.7附带的VDA相同,因此升级到7.7还应包括7.6 FP3的修复程序
如果您遇到/怀疑它们,使用XD7.6绝对值得阅读其他问题 - #LC2931是您可以用来与Citrix支持讨论的错误号和参考。
我相信任何没有支持的Citrix客户都可以针对已知/已确认的问题提出机票,如果已知问题将退还该机票。

以下为原文

Following up with Citrix, they advised us of some issues fixed in XD 7.6 FP3 - if using XD7.6 it's probably worth checking this in http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-6/xad-whats-new/feature-pack-3--vda-for-desktop-os---fixed-issues.html

In particular the lossless indicator issue indicated by Jason is likely to be:

On VDAs with HDX 3D Pro enabled, the lossless indicator taskbar icon (for LLIndicator.exe) might fail to indicate the lossless state and might not respond when right-clicked.
[#LC2931]

VDA 7.6.300 is the same as the VDA that comes with 7.7 and so upgrading to 7.7 should also include the fix as per 7.6 FP3

It's definitely worth reading the other issues if using XD7.6 in case you encounter/suspect them - the #LC2931 is the bug number and reference that you can use to discuss with Citrix support. I believe any customer of Citrix without support can raise a ticket on a known/acknowledged issue that will be refunded if a known issue.

瑞秋,
phite描述的问题与你描述的问题不同。
#LC2931:这是我报告的,当右键单击LLIndicator时,没有弹出窗口可以选择LossLess模式。
在FP3中仍然可以看到Explorer.exe占用5%-10%CPU的问题。
如果您查看ProcMon,它会不断向注册表查询一些NVidia密钥。

Rachel,

The issue described by phite is different from the one you describe.
#LC2931: This was reported by me, when right clicking on the LLIndicator there was no popup to select LossLess mode.

The issue with Explorer.exe consuming 5%-10% CPU is still visible in FP3. If you look in ProcMon it is continuously querying the registry for some NVidia keys.
