1.10.0 TV Server stops working randomly / Server cant be found (1 Viewer)

[Russ_T_]

MediaPortal Version: 1.10.0

Description
After upgrading from 1.9.0 to 1.10.0 TV server stops randomly or the connection to it is lost.

MP displays a message: (see attached)
Window Title: TV Setup
Please specify the IP address or host name
of the master TV service
Current Setting:
HTPC7

HTPC7 is the name of the PC, both the client and the TV server are running on

Exiting MP, and restarting it resolves the problem, however in the interim scheduled TV shows are not recorded

I have tried amending the hosts file as per the known issues
(un-commented 127.0.0.1 etc)
Running on Windows 7 Ultimate SP1
Didn't have this problem on version 1.9.

Steps to Reproduce:
Using MP normally - mostly to watch recorded TV
Turn off TV, go away, come back later, turn on TV - problem appears
Appears random. no pattern to why it happens
Has been happening randomly for several weeks. sometime multiple times a day, other times after several days. Sometimes also happen while we are watching a recorded program

Please check your power settungs. Maybe they have changed with the update and the server goes asleep. (Happens to my server, but it is a multiseat installation and i makes sense in my surrounding).

Hi Schwarzrz. I checked the power settings. CPU and Monitor are always on - never goes to sleep or standby. This is a dedicated HTPC server.
Thanks.

I am thinking of going back to version 1.9.0.
If I just run the 1.9.0 installer will that work?[DOUBLEPOST=1422299111][/DOUBLEPOST]Also I tried setting the wake on lan settings in MP Config, to see it that would fix the problem - but it didn't help.
( I set the WOL timeout to 30 seconds, and left the "auto configure server MAC address" ticked )

Russ,

1.10 introduced some changes in display management. On some systems there are issues when the PC resumes from standby. You may want to try the following patch and see if this helps: Link

The file "MediaPortal.exe" contains the main change. The other dll's address the "running in wrong thread" error. All files are located in the MediaPortal directory (some in the plugins section). rename the originals and copy the patches to the same locations.

regards,
HTPC_Sourcer

The TV service does seem to be stopping due to this error:

How many schedules do you have?

I had this happen a few times, had to restart TVServer manually. I rebooted my system after the last couple occurrences and it has been over a week since the last time. I don't let my PC go into hibernation or standby, so that's not the issue. I remember I did cull a couple schedules from recordings, so maybe that was part of the fix.

Thanks everyone for your replies

There are 143 scheduled recordings

I re-installed MP 1.9.0, and rebooted my PC.
However the problem still exists. I came home from work today and the same error appeared.
Restarting MP fixed it - but some programs were not recorded.

Also I have had a couple of instances when the system seems to have frozen (once while watching a recorded TV show).
The mouse still works but nothing else is responsive, including a Ctrl+Alt+Del. However after waiting about 30-40 seconds, the system came back to life and MP and everything else seemed to work again.

This is odd as I haven't done any system upgrades or installed any new software etc.
There is no backup or virus scanning scheduled during this time. And the system is setup so it never suspends / goes to sleep etc.
I have been using MP successfully on this same hardware / windows platform for about 3-4 years.

That's quite a lot.
Have you added some since upgrading from MP 1.9 to 1.10? ...because I suspect this may explain the problem.

 

[Russ_T_]

I may have added a few, but not a lot. I do recall also deleting a few recently.

I will delete some more and see how it goes.
Is there a recommended upper limit ?

BTW I have 2 Hauppage cards - each with 2 tuners - so 4 tuners in total.
I always set my recordings to start 1 minute before, and finish 10 minutes after - so there is sometimes an overlap .
However Its been this way for the last 3-4 years and has been OK until recently. (MP rocks !!!)

I will let you know how I get on after deleting some scheduled recordings.

Thanks

Not as far as I'm concerned. However, the fewer the better.
