Hello,
I have a few months old system with vdr 2.0.6. VDR is used only as a
backend for xbmc (via xvdr plugin).
Everything works fine except for a few lags which I tracked to VDR
creating new channels every now and then. When I checked the channels
I noticed there are duplicates (there are 36374 channels and many of
them are there about 500 times). I wouldn't be surprised if vdr would
suffer performance problem with such number of channels.
See the setup.conf (not changed in months), syslog and part of
channels (got by LSTC command) and stats:
https://gist.github.com/juriad/2b635ef475a6ddf829ab
Why VDR creates duplicate channels?
Is there problem with my configuration or is it a bug in vdr?
What other information shall I provide?
Looks like VDR doesn't find an existing channel in its Channels list
when it encounters a new version of the SDT. At the moment I have no
idea how that could happen.
Is this a plain vanilla, unpatched version 2.0.6 of VDR?
Klaus
Yes, it is unpatched version (just checked diff againts
vdr-2.0.6.tar.bz2).
I tried to use gdb to see what is happening.
Anyway, the backtrace of call of method cChannels::NewChannel is:

I tried to create a core-dump but gdb failed to do so.
Maybe you can add some debug output when a channel named "CT 1 HD" is
encountered in the SDT and then searched for in the Channels list.
Since the channel apparently *is* in the list, the search for it
seems to fail at some point. We need to find out the reason for that.
Klaus
Is there any progress?
Maybe my problem related to this too. I just jumped from vdr-2.1.6 to
the 2.1.8 and now I have many false OBSOLETE channels.
For example, i have channel (svdrpsend printout):
875 TV11:11804:hM2O0S0:S4.8E:27500:6001=2:6002=@3:6006:90F,93E:6000:86:8:0
but this and any other channels on that transponder marked as OBSOLETE:

At the same time this problem not occurred with DVB-C channels.
250 2 ETV2:266000:C0M256:C:6875:300=2:310=est@3,311=est@3:0:B00:1004:16:1:0
In the DVB settings UpdateChannels = 4 selected.
