Yes, they happen a few times a day... I'll try to setup an environment to test this version and report back any results. I don't want to sound negative, but I have doubts that this issue could be already fixed in darcs... Analysing the valgrind backtraces, it seems to be related to concurrency. For example, if you look at nua_server_request_destroy(), invoked from nua_session.c:2573 in the first valgrind trace I sent, it sets 'sr->sr_irq = NULL' in nua_stack.c:1492. Then, afterwards, when the invalid read occurs, there's a test to check if 'sri == NULL' in nua_session.c:2890, which fails, because the invalid read occurs in line 2893. How many threads does sofia start internally? Doesn't it look like there's a race condition in that piece of the code? Thanks again.
