Hi,
I have problems with netcat of a big lscp file (~250 lines).
Sometimes happens that the loading stops before the end. It seems that
netcat is too fast.
So I wrote this bash script that introduces some latency between every
line that is sent to LS:
#!/bin/sh
while read line
do
if [ "$( echo "${line}" | head -c 1)" != "#" ]
then
echo "${line}" | netcat -q 0.01 localhost 8888 &
sleep 0.1
fi
done < $1

i have tried all kinds of netcats and combinations of invoking the config file but non is 100% relieble when i try to load it using bash script or systemd at startup..for example i have 27 channels and 27 instruments..it stops at 24 or 26.. |

You mean the LSCP server freezes? CU Christian |

no..it just doesnt complete the config loading..its like if it never comes to the server..

It's very unlikely that this misbehavior could be a bug in netcat, bash or the TCP/IP stack of your OS. It rather sounds like a bug in the sampler's internal instrument manager or the LSCP server. There are various individual tasks inside the sampler for which separate threads are spawned. And if there is some kind of bug regarding the synchronization between those threads (of the sampler) it can lead to such a misbehavior. So debugging this issue on sampler side would be preferable, to get some informations what's going on when this misbehavior occurs. CU Christian |

is there a way to see what did sampler recive before it has send its data for loading....?

Sure! Recompile the server with increased debug level:
./configure --enable-debug-level=2
make
Debug level 2 like suggested, should be enough for this. Then run the sampler
(no need to install it):
src/linuxsampler
Then it should show a debug message for every LSCP command recognized by the
LSCP server (see src/network/lscpserver.cpp).
In the sampler's source code you see debug messages are placed like this:
dmsg(2,("This is some value to debug: %d\n", value));
The number in front indicates the minimum debug level for the debug message to
be printed to the console.

I forgot to mention that:
- I successfully load the .lscp if I open it with QSampler and Fantasia.
- I also successfully load the .lscp with netcat if I set netcat -i 1
(-i 1 means that netcat waits 1 second between each line of text, but
unfortunately you can't tell netcat to wait less than 1 second, so it
will take too much time to finish).

Those have a "natural" delay between sending the LSCP commands, since QSampler and Fantasia are also executing their UI code in between. > - I also successfully load the .lscp with netcat if I set netcat -i 1 > (-i 1 means that netcat waits 1 second between each line of text, but > unfortunately you can't tell netcat to wait less than 1 second, so it > will take too much time to finish). And which type of LSCP commands fail actually? A simple cat whatever.lscp | netcat localhost 8888 "should" always work without problems. If not, then it is most probably a bug in the sampler, which should be fixed. My guess is that it might be something about MIDI instruments. CU Christian |

I tried with debug-level=2 several times, but the problem didn't occurs. To make it occurs, I had to compile linuxsampler with the following options: ./configure --enable-debug-level=2 --enable-refill-streams=2 --enable-stream-size=320000 --enable-preload-samples=65536 --enable-max-voices=200 --enable-max-streams=220 I found these options here: http://www.linuxsampler.org/debian.html The differences between the two versions are: # Preload Samples: 32768 - (the latter version has 65536) # Streams to be refilled per Disk Thread Cycle: 4 - (the latter version has 2) # Default Maximum Disk Streams: 90 - (the latter version has 220) # Default Maximum Voices: 64 - (the latter version has 200) I attached a .tar.gz that contains the lscp file, and three different logs where you can see that the loading stops before the end.
