That report showed me 2 leaks.

1) in mod_cdr_sqlite where it was expanding a variable template and not checking if it needed to free the results.
2) in mod_dptools in the user channel code.

Wait, there's more.

Fixing the leak in the user channel then led me to realize there was a regression in the change that introduced that leak that was breaking the code that copies all the variables from the {} into the far end channel.

anyway, try out GIT head.

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?

Thanks,
