HD STation & Plex Server draining CPU

[simonz21]

Can anyone explain to me why HD Station & Plex are using so much CPU? Yesterday I had to shut them down as they were draining 100% CPU at 6am when no one had been watching Plex for hours. This morning they are still consuming up to 80%.

Any suggestions?

About HD_Station 3.2.1 is a known problem as father_mande said.
So about plex now, the only reason to consume so much CPU while no one watches could be a scheduled task for refreshing libraries.

I tried restarting HDS and stopping Plex Server, but this didn't reduce hdsfusemnt at all. A total reboot helped for a while and everything was normal, but even now hdsfusemnt is consuming up to 25-50% CPU, with plexhometheater taking another 15-25%. And I haven't watched anything on Plex for a couple of days, nor changed any of the files/folders.

Process Name User PID Status CPU Usage Memory
plexhometheater admin 6336 Running 12.56 % 8.3 MB
hdsfusemnt admin 27310 Sleeping 25.88 % 131.5 MB
kernel_processes admin 0 Running 4.52 % 0 KB

Are there any practical solutions to stop this high-burn CPU?

I'm having the same problem on a TS-453A.

The problems started when I updated the firmware to 4.3.3.0361 Build 20171101 and then updated HD Station.

At the moment hdsfusemnt is using 51% CPU and 512MB memory.
Using lsof on it reveals the following information:
It has 3495 open file handles a small sample of the open files is shown below:

Clearly something is very wrong with it.

I'm having the same issue with my TS-251A. I've tried restarting HD Station (several times), uninstalling and rolling back to version 3.1.C. Unfortunately when I did that it wouldn't let me re-install Plex Home Theater. I've sent a trouble ticket in to see what they say. Hopefully this is something they can fix.

Hi,
I´m having the same issue.
NAS Model: TS-453 Pro
QTS: Version 4.3.3.0361
HD Station: 3.2.1

It takes a lot of memory and high CPU Usage:
Process Name User PID Status CPU Usage Memory
hdsfusemnt admin 5529 Sleeping 34.49 % 1.5 GB

I will open a ticket also to push QNAP stuff to solve it.

Best regards.

@dolbyman
Where can I get the previous version of HD Station?

Will that effect anything installed such as Plex? I know that when I tried uninstalling HDS and reinstalling 3.1.c if wouldn't let me install Plex Home Theater until I updated HDS again.

[simonz21]

I've raised a ticket and pointed QNAP to this thread, so hopefully someone will take a look and make a suggestion.

[carrisr]

I was able to downgrade to 3.1.C and it does seem to reduce the CPU load. Now HD Station is using less than 1% idle and 254MB with no running apps. I haven't heard anything back from support yet. Interestingly, the revision history page for HDS doesn't list version 3.2.1, so it's unclear what the upgrade is supposed to do.

[Max1mizer]

Same issue here with 3.2.1 getting annoyed. Backed to 3.1.C - no issue.

3.2.1 was taking 35% of my CPU and officially 3GB RAM looking on the process list, while system claimed 75% of my RAM (16GB) is used and separate exchange swap file has to be created (lol).

Now it's 1% CPU and 6% of RAM is being used with 3.1.C

Additionally when I was trying to get to my Video library it was so slow reacting on 3.2.1

[simonz21]

QNAP fixed it! No idea what they did as had to provide them access via Helpdesk, but they did something, because this morning there is no FUSE drain at all:

Can you give me your HelpDesk Ticked ID, so I can raise the same instead of all the time closing poping-up window with "New HybridDesk Station Now update" ?

But I'm not using PLEX. My problem is with this process :
