[OpenSIPS-Devel] pkg_malloc leak with 1.6.3-tls (set_dst_uri/get_all_bodies/new_part)

[Chase Venters]

Greetings,
    I've been seeing a pkg_malloc leak in my production OpenSIPS
instances. I followed the memory debugging advice and built my own RPMs
with memory debugging, then obtained dumps after several days of
production traffic.
    The full memory dump is huge... I'd be happy to zip it up and put it
somewhere, but it seems to me that the bulk of allocated memory is
between these three functions / allocation sites:

    I am attaching the template we use to generate our OpenSIPS route
scripts on our production servers. Note that we're not seeing a tm,
dialog or shm memory leak.

Thanks,
Chase
