Hello,<br>
<br>
I found some cases when variables were not freed, but I cannot test
as I am not using unixodbc.<br>
<br>
Can you cherry pick the patch:<br>

<br>
and see if not all goes ok? If not other issues, then I will
backport.<br>
<br>
Cheers,<br>

I am also using db_unixodbc for all database accesses (with
MySQL backend). The problem is that after a few hours, a single
Kamailio process (never more than one) starts complaining that
it has run out of memory: <br>

I have attached the stderr output when I kill the offending
process. From what I can see, the memory leak somehow involves
database allocations that fail to be freed, consuming more than
3 MB out of 4 MB allocated: <br>
<br>

I have the setup to compile my own RPMS, and I intend to track
down the memory leak on my own. However, I would like your help
in focusing my search, on whether this is a known issue, or
where in db_unixodbc should I look. <br>
