you're killing me ;) Thanks, I'll let it run a bit longer and as I'm such a daredevil, I added a cue_cut() on my lists and testing that along. I'm running on a CPU craziness (will make an issue for it should I spot it more precisely) as well using replaygain extraction, does it use the same logic?

I'm back on sox for testing... If I only use output.external, it lasted for
more than 4 hours which was a first... so I added pipe_metadata from

but it failed after 10+ hours...
Code was:
```
s = smart_crossfade(playlist("test.m3u"))
s = mksafe(amplify(1.0, s))
pipe_file = "test.pipe"
pipe_input = pipe_metadata("test.pipe", s)
ps = output.external(id='pipeout', %wav, "sox -t raw -b 16 -c 2 -r 44.1k -e

Re: [Savonet-users] [savonet/liquidsoap] Liquidsoap freezes on a complex script (#609)
@gilou, thanks for reporting this. You're on the latest code right? It seems that the streaming thread is blocked but the other treads are still responding. One thing you can try is to get a `gdb` backtrace of the running process: ``` % gdb > attach > thread apply all bt ``` -- You are receiving this because you are subscribed to this thread.

Re: [Savonet-users] [savonet/liquidsoap] Liquidsoap freezes on a complex script (#609)
aand it froze again, after 5 hours.. Same symptoms, liq is somehow frozen, stills responds on its socket but doesn't actually handle anything, yet it responds to SIGUSR1 (truncates the logfile) and closes on other signals (ABRT, HUP..). -- You are receiving this because you are subscribed to this thread.

and interestingly (or not), liq honored USR1 in that state, because it truncated the log file upon receiving! -- You are receiving this because you are subscribed to this thread.

if I attach strace to stereotool, it seems to be alive and waiting for data... `[pid 30093] read(0, ` -- You are receiving this because you are subscribed to this thread.

Re: [Savonet-users] [savonet/liquidsoap] Liquidsoap freezes on a complex script (#609)
I removed all outputs but the one streaming the piped stream, as I suspect it's
the culprit, it froze again after 1h40, smart_crossfade managed to squeeze one
more line:
`2018/08/22 12:06:31 [smart_crossfade:3] new >= old + margin, old <= medium and
new <= high.`
This time I had a socket connected before, and it's responding...
```
uptime
0d 01h 53m 51s
restart
restart called
```
but it's not doing anything
the external process is still running, hasn't crashed, doesn't complain on
stderr
If I attach strace to liq, I get:
```
sudo strace -fp 29444
strace: Process 29444 attached with 7 threads
[pid 29454] futex(0x56309c3428a0, FUTEX_WAIT_PRIVATE, 2, NULL

[pid 29448] futex(0x7f93dc000b48, FUTEX_WAIT_PRIVATE, 0, NULL

[pid 29446] <... select resumed> ) = 0 (Timeout)
[pid 29446] select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=5}) = 0 (Timeout)
[pid 29446] select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=5}) = 0 (Timeout)
[pid 29446] select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=5}) = 0 (Timeout)
[pid 29446] select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=5}) = 0 (Timeout)
[pid 29446] select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=5}) = 0 (Timeout)
```
If I kill the external process, liq uses 100% of CPU.
I'll try and monitor the external process next time.
I added merge_tracks and drop_metadata to try making stereotool happier, but I
don't think that's the issue ☹
