"No symbol table info available." - You don't have tvheadend binary with the debugging symbols.

Sorry about that. I'm not into debugging most of the times. But I think this should do it.

Do you have file named a9fe5bf8136f89ab0a9417f67d581f2a twice in your config tree ?

I've got those files:
./dvr/autorec/a9fe5bf8136f89ab0a9417f67d581f2a
./dvr/log/a9fe5bf8136f89ab0a9417f67d581f2a

It's wrong. Remove one.

At least tvh is not crashing anymore, but it's consuming quite a lot of CPU and it looks like it is busy or freezing. I will keep it running for a while to see if this fixed the issue.

Strange thing is that this duplicate file is there since 6 November.

I've reboot my machine and it looks like tvh is stable again. Thanks for your help again.

I have a backup of the old config.

The file dvr/autorec/a9fe5bf8136f89ab0a9417f67d581f2a is the autorec file of a program I record on each weekday.
The file dvr/log/a9fe5bf8136f89ab0a9417f67d581f2a is a single recording of the same show recorded on 6-11-2015.

Is this what you want to know? If you like I can also share the backup I made. If you need other informations, please let me know.
