[Linuxsampler-devel] Possible Bug report - LinuxSampler Windows, latest weekly build

[Graham G. <ggo...@gm...>]

I recently released a jOrgan - LinuxSampler Theatre Pipe Organ sample
set to some Alpha testers, and we have an issue with LinuxSampler
standalone crashing.

Lynn Walls describes it as follows:

I conducted some more experiments on this problem. The sequence is as follows:
1. Start linuxsampler back-end.
2. Start "client" and run the Barton ASIO4ALL .lscp script
3. Shutdown "client".
4. Re-launch "client" and run the script again on the same
    running instance of the linuxsampler back-end.
5. Some kind of crash occurs immediately after all the
    "Freeing..." messages have displayed (likely as a result
    of the RESET command).  Something in what happens AFTER
    the RESET seems to cause the crash...but no indicative
    messages appear in either the back-end or the "client".

Here are the test results specific to each "client":

   "Client"   Test Results
-----------  ---------------------------------------------------
jOrgan       back-end crashes and/or jOrgan crashes and system
              hangs; System must be re-booted after physical
              power-off.

QSampler     QSampler crashes, but back-end may be terminated
              with Ctrl-C, and system continues to run normally
              (does not hang/freeze).

JSampler     System hangs/freezes...no messages or dialog boxes;
              system must be re-booted after physical power-off.

The freeze/hang of the whole computer bothers me in terms of whether
or not this is a
wholly a linuxsampler problem or a combination of linuxsampler and a
MIDI open/close
problem.  I have seen other situations where a catastrophic crash or
hang of a program
that has opened one or more MIDI devices with hang/freeze the whole
system.  Sometimes the system instance can be saved, using taskmanager
to kill the offending apps, and sometimes nothing but a re-boot works.

-----------------------------

Is there a log file that we could load to see what is happening? Or
something else that would help find out what is happening?

Kind regards,
GrahamG

Can you send me this script?

I couldn't reproduce exactly the same behaviour, but I did find a bug in
the LS MME midi driver. When you delete the LS driver (as is done by the
RESET command for example), the midi connection wasn't closed properly.

Please test if the problem is gone with the latest version
(linuxsampler_20130509_setup.exe).

I'm sorry I haven't contributed any bug reports, but it doesn't happen consistantly enough to reproduce dependably, and I've always been buisy with musical projects at the time, and never took the time I should have. On both WinXP and Win7 for quite awhile, when using big config files with around 32 or so channels, if something goes wrong, I've always been better off to kill everything and start over. Running the .LSCP file again would often cause a lock-up, or at least generate errors about devices that couldn't be created. I must try a new update and see if this takes care of my difficulties also. Thanks all for so much good work on such a great project.
