Thanks for your response. I don't know what glibc version this user has.
I have asked. But I doubt it is an old version as I believe he is
running NPTL instead of LinuxThreads.
The thread that actually hangs in the pthread_join() is not the
thread that was handling the RTP packets. The hanging thread
destroyed the SingleThreadRTPSession object thereby killing the
RTP thread. From the backtraces I have received it seems that
the RTP thread has exited (maybe even before the RTPSession object
is killed; I can't tell. So I would expect pthread_join()
to return immediately. I will see what more information I get
to solve this problem.

Which version of glibc was the target platform under? I have seen very
odd problems like that in rather old glibc's, perhaps around the time of
Debian woody, with the older linuxthreads stuff, when a thread
terminates itself by exiting, and something later then tries to join
with it.

Hi,
I hope this mailing list is still alive. It has been very quiet here
recently.
A user of my SIP softphone Twinkle reported a deadlock situation to me.
The function backtrace showed the following:
#0 0x0000003f88f07105 in pthread_join () from /lib/libpthread.so.0
#1 0x00002aaaab008b48 in ost::Thread::terminate ()
from /usr/lib/libccgnu2-1.3.so.1
#2 0x0000000000575f70 in ~SingleThreadRTPSession (this=0xb5e420,
__vtt_parm=0x5c9b48) at rtp.h:456
#3 0x000000000057686e in ~t_twinkle_rtp_session (this=0xb5e420)
at twinkle_rtp_session.h:10
Somehow it seems that the RTP session thread gets stuck in
pthread_join() forever.
Has someone else experience this problem? Or does somebody knows
how to solve it?
The problem is that I cannot reproduce this problem on my own
machine, so it is a bit hard to debug :-(
Best regards,
Michel
