I'm also having problems with the pool. I didn't send
anything to the list because I'm trying to make a
small sample application to show the problem. But,
since the subject came up, this is whats happening:
I am playing a wav from the EOF CallBack, creating the
wav players with PJMedia API and not with pjsua. Just
to test and see if it was something in my code I tryed
playing the wav from a timer with 0 ms so it is done
from teh thead "pjsua" and not "clock" as the EOF
Callback and it works with no problems. I had the
following stack when the problem came up:

in all cases I get the following message after the
crash:
*** glibc detected *** malloc(): memory corruption:
0x09ea27c0 ***
changing just the hex number in the end. It always
happens just after the call to the function that
creates the wav players in my application, when called
from the "clock" thread. It happens after a large
number of calls (between 500 and 5000) and if I have
many concurrent calls at a time (I used sipp to test
with 20 call/sec and around 100 concurrent calls). I
know there is a problem with playing wavs form the eof
callback that can lead to a deadlock, but I am
avoiding this by saving the media port in my
application and updating it only when a media event
occurs. I tested my code with API 0.8.0 and 0.7.0 and
in both cases the problem rises, and when I used the
timer trick there was no problem. I'm writing a small
sample code to reproduce the error (in case it is
really there...) and will make it available.
Thanks for all support that I am getting,
Thiago
