I did a small valgrind test with git HEAD: 1. turn on, make 5 calls or so 2. leave FS on for the night (without calls) 3. shut it down cleanly in the morning During execution, some "Warning: invalid file descriptor -1 in syscall close()" (4-5 for each call + some extras). After shutting down, something strikes me in the vg.log file: "definitely lost: 173,407,885 bytes in 84,680 blocks" Is this normal? valgrind log: http://pastebin.freeswitch.org/17779 Thanks, François.

valgrind is your best bet:
valgrind --tool=memcheck --log-file=vg.log --leak-check=full --leak-resolution=high --show-reachable=yes /usr/local/freeswitch/bin/freeswitch -vg
run this on normal traffic for a while and get the log file.
if you unload mods it would not help with a leak but it would with a swelling pool.

I'm experiencing what I think is a memory leak in a production system with a recent git (2-Nov), with FS consuming >5GB and increasing after a few days with never more than 10 calls at once.
While the users are not experiencing problems so far, I'm a bit worried. So I have a few questions:
- How can I be sure it's a leak and not some memory pool thing that FS would free when the system needs (system has 10GB total)?
- If I unload modules one by one, is the memory used by this module freed immediately?
- What would be a "good" way to try and narrow down the cause? Is valgrind a good tool for that?
Of course I'll try with GIT HEAD and try my best to find the cause before considering to add a new Jira issue, otherwise it's quite useless.
Thanks, François.
