[xine-devel] Why did xine hang starting up a udp: stream?

[Barry S. <bar...@on...>]

Here is are the stack traces for all the threads in xine that has just 
opened
a udp://239.x.x.x:ppp MRL. I've seen this pattern twice now and think that
the important thing is in Thread 5 that is waiting for a buffer and I assume
not getting it.

Thread 5 (Thread 78265264 (LWP 2512)):
#0  0x0057a402 in ?? ()
#1  0x00386a1c in pthread_cond_timedwait@@GLIBC_2.3.2 () from 
/lib/libpthread.so.0
#2  0x0031bf0b in ao_get_buffer () from /usr/local/onelan/lib/libxine.so.1

Is this a code problem or a config problem? Where should I investigate 
to get more
insight?
