MythTV General Discussion and Support

strace all those troublesome PID's to see what they are getting stuck on.

Can you give me some help on how to do that ? Thanks

grab a PID, like 2253 from you example.


And run:

sudo strace -p 2253

If it is quiet, it is probably forking off to child process, so try:

sudo strace -f -p 2253

You can limit what info strace returns, for eg adding

-e trace=file

for file calls only.

man strace

will help you out.

Thanks for that, will try that when I find some time.

In the meantime I have found a bit more on this on the web, looks like it's quite a common problem. No neat solution so far, though. Different people have different workarounds (cronjobs to kill multiple instances of mythlogserver or mythlogserver processes above a set CPU percentage, disabling mythlogserver altogether by changing file permissions), none of them real solutions, though.

At the moment I disabled mythlogserver by changing the executable flag of the file:

chmod a-x /usr/bin/mythlogserver

Not a good workaround but at least it keeps my system from getting clogged and sluggish.

Damn!
That sucks.
Is there a bug logged about this?

If not, I'd suggest you do it to help others with this (and me so I don't have to face this by the time I upgrade )

Yes there is, don't have the link atm (on my mobile). There hasn't been much feedback or obvious activity from the developers yet, though

Ahh ok. That's the best you can do. Shame this problem exists.

I don't know if this is a mythtv problem or a hardware problem but when I have my mythbox connected to my tv (Samsung Series 7) it can't detect my Samsung Blu Ray player using Anynet+. As soon as I unplug the mythbox the blu ray player is detected.

Does anyone know if this is an issue with mythtv itself and if there is a fix for it or is it a hardware (gpu, tv etc) problem?

It's possible it could be a feature with the tv that locks out all anynet+ devices if an incompatible device is detected. I know it isn't the cable because I have switched them and it all still works as long as the mythbox is not plugged in.

It's extremely unlikely MythTV is doing anything to affect this. I'd say even having your PC connected without MythTV running will produce the same issue.

Don't know anything about Anynet, but is your TV one of those ones that technically only serves up one port as port XYZ even though there are two ports that can be assigned to it? Basically one always has priority over the other.

I think you're right. It also does it when the pc is off. I think I remember testing that (it was about 1:30am so I can't remember fully what I did).

My tv has 3 HDMI ports and no matter which port the blu ray was in, if the pc was connected the blu ray wasn't found. I tried every port combination.

We've ruled out mythtv being the cause so I might move this to another thread somewhere to avoid getting off topic. However, I'm wondering if there is something I can install to get my mythbox to be detected.
