Description Mickey Gee 2009-09-23 21:41:02 UTC 
While playing a flac file on a Boom being controlled by a Fab4, the Boom quit playing the track (some Enya track we've played millions of times). When I checked my SbS, it had completely stopped running. I had to restart it manually. Once I did, it was running again.

Looking in the server log, here's what it says when it crashed:

[09-09-23 17:37:26.0233] Slim::Utils::Firmware::downloadAsyncError (557) Warning: Firmware: Failed to download http://update.squeezenetwork.com/update/firmware/7.4.0/fab4_7.4.0_r7713.bin (404 Not Found), will try again in 640 minutes.

The line at 19:17 is the crash. The line above and below are just for context.

Running Windows XP SP2 on my Lenovo S10e Netbook with 1GB RAM.
Comment 1 Alan Young 2009-09-23 22:15:46 UTC 
Mickey, what revision of SC.

Andy, Could there be a problem with the latest rebuild of the Audio/Scan or Flac libraries for that platform?
Comment 2 Mickey Gee 2009-09-23 23:03:50 UTC 
Andy had also updated test.sn.com server at the same time this occurred. During that time, it was unavailable. Not sure if that's relevant.

Revision v7.4.0, r28603 of SC
Comment 3 Andy Grundman 2009-09-24 04:50:25 UTC 
Eek, so it crashed when you were trying to seek in your FLAC file?  Can you reproduce it?  Try enabling player.source=INFO debug and seeking a lot of times.  If it crashes again, get the debug lines right before it crashed, and also upload the file.  Hopefully I will be able to reproduce it with that info.  I'm not sure there is a suitable debug line showing what the seek value is though.

Bug 14241, additional debug line showing what call was made to findFrameBoundaries
Comment 5 Andy Grundman 2009-09-24 04:57:41 UTC 
I've added a debug line right before the seek call.  Please use build 28625 or later when getting your log.
Comment 6 Mickey Gee 2009-09-24 15:40:28 UTC 
Was able to repro on Fab4 controlling Boom, but not on Jive or Boom front panel. On flac track, use Fab4 touchscreen to seek within track.

Changing bug priority. 

Here's the trace requested:

Comment 7 Andy Grundman 2009-09-24 16:03:16 UTC 
Thanks, did you have player.source set to INFO though?  It doesn't look like there are any source messages there.

I think that his is probably just luck. The mechanism is the same in all cases. What about when using the WebUI?

Probably ought to be 7.4.1 but not with top priority.

Failing FLAC file.

Here's a player.info log of a short FLAC track that caused the problem. Note that I've reproduced the problem with different tracks. 
[09-10-01 13:13:19.5425] Slim::Player::Song::open (446) Opening stream (no direct streaming) using Slim::Player::Protocols::File [file:////EssexHouse/Music/FLAC/J.K.%20Rowling/Harry%20Potter%20and%20the%20Chamber%20of%20Secrets/001%20Introduction.flac]

What I did was to start the track playing then use forward and backward to reposition the track. Often it would fail after the first change in position, but it always failed within 4-5 attempts.
Comment 10 Andy Grundman 2009-10-01 11:29:19 UTC 
Great, thanks, I can reproduce it now. :)
