Roddie Kieley commented on PROTON-2231:
---------------------------------------
Investigation ongoing. Seeing two variations of the hang at the end of the
threaderciser using the following on a 6 core i7 based mac:
{code}
for i in {1..10}; do `echo echo $i; date +%H:%M:%S; ./c-threaderciser -time 10
-threads 12`; done;
{code}
This hangs the very first time it runs in many cases in one of two places
{code}
for (i = 0; i < threads/2; ++i) pthread_join(proactor_threads[i], &ignore);
{code}
with 6 of the 7 threads sitting in pn_proactor_wait
OR threaderciser hangs at
{code}
global_destroy(&g)
{code}
which itself is hung on
{code}
pn_proactor_free(g->proactor);
{code}
As well I also see the Assertion failed from the above comment periodically.
More investigation and understanding required to put the pieces together.
