Summary	0007980: Occasional random crashes probably when setting up connections
Description	Mutex assertion fails in libs/ardour/delayline.cc:292. This happened to me maybe 15 times this week. One time I happened to capture a backtrace: ardour-6.0.pre1.15: ../libs/ardour/delayline.cc:292: bool ARDOUR::DelayLine::set_delay(ARDOUR::samplecnt_t): Zusicherung »lm.locked ()« nicht erfüllt.

Steps To Reproduce	1. Get some (short) audio file (jingle or a drum sample). 2. Create 500 symlinks to that file (for i in `seq -w 1 500` ; do ln -s filename.wav filename-$i.wav ; done) 3. Create an Ardour6 session using a dummy interface (not jack, because then 0007975 jumps in) with the same sample rate like the sample file. 4. Open the import dialog and select these 500 symlinks and click "Import" Ardour then imports 500 times the sample. Chances are high that the issue triggers on of the 500 times.

x42 2020-04-06 04:31 administrator ~0021201	This is caused by jack2 updating port latencies while processing, and likely has to be fixed there. The assert() will only trigger in debug builds, optimized builds will worst case experience an audible glitch.

x42 2020-04-06 04:33 administrator ~0021202	PS. This is not a bug per se, I've explicitly added that assert() to track this down. It also happens occasionally when loading a session.

paul 2020-04-12 21:03 administrator ~0021319	I think that a "thread apply all bt" would be useful here to get some idea on which other thread has taken the lock.

x42 2020-04-12 21:11 administrator ~0021320	This happens when the process-callback runs the delayline, while another thread changes the delay. The delay-time can only change the processors are being configured, or the route I/O latency changes. Yet both of these operations are supposed to be exclusive with processing. Which is why the assert() was added.

johmue-eo 2020-04-12 21:29 developer ~0021321	I attach a backtrace for all threads.

x42 2020-04-12 21:42 administrator ~0021322	That is an odd backtrace it's the first one that I've seen that doesn't show any other thread in Delayline::*

x42 2020-04-25 16:29 administrator ~0023915	This should be fixed since 6.0-rc1-102-g02e5605cdd Please test!

johmue-eo 2020-04-25 19:52 developer ~0023917	Sorry, it has gotten worse. I cannot trigger the crash any more by importing multiple files. But that's only because I can no longer import multiple files at all. I start by "./gtk2_ardour/ardev -D latency -D latencycompensation" I can import one file at once, but when I try to import more than one at once, the following output appears and the UI freezes.

x42 2020-04-25 23:28 administrator ~0023923	OK, that seems to be another issue with JACK... which I cannot reproduce :(

x42 2020-04-26 00:05 administrator ~0023924	@johmue-eo Could you get a backtrace when it hangs or assert()s?
