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?
Thanks for your help.

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?

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: #0 cChannels::NewChannel (this=0x76b800 <Channels>, Transponder=0xf992a0, Name=Name@entry=0x7f74ce78fdf0 "CT 1 HD", ShortName=ShortName@entry=0x7f74ce790df0 "", Provider=Provider@entry=0x7f74ce791df0 "Towercom", Nid=Nid@entry=3, Tid=3234, Sid=4901, Rid=0) at channels.c:1013 #1 0x00000000004d64ee in cSdtFilter::Process (this=0xf9aa40, Pid=<optimized out>, Tid=<optimized out>, Data=<optimized out>, Length=<optimized out>) at sdt.c:105 #2 0x00000000004d727c in cSectionHandler::Action (this=0xfa41e0) at sections.c:211 #3 0x00000000004f8b23 in cThread::StartThread (Thread=0xfa41e0) at thread.c:262 #4 0x00007f74d79920a4 in start_thread (arg=0x7f74ce794700) at pthread_create.c:309 #5 0x00007f74d63acccd in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111
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.

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:
