Hi there,
I'm observing serious memory leaks when using Sofia-sip 1.12.7 . I
have a simple UAS test program with a NUA callback like:
void event_callback(nua_event_t event,
int status,
char const *phrase,
nua_t *nua,
nua_magic_t *magic,
nua_handle_t *nh,
nua_hmagic_t *hmagic,
sip_t const *sip,
tagi_t tags[])
{
switch (event) {
case nua_i_invite:
nua_respond(nh, 180, NULL, TAG_END());
nua_respond(nh, 200, NULL,
SIPTAG_CONTENT_TYPE_STR("application/sdp"),
SIPTAG_PAYLOAD_STR(g_sdp),
TAG_END());
break;
case nua_i_bye:
nua_handle_destroy(nh);
break;
default:
break;
}
}
When I link this program against sofia-sip 1.12.6 I can keep it
running for ages with 350 caps and the memory usage never goes above
6% in a 2 GB machine. With 1.12.7, 100% memory is used after about 10
minutes.
My test setup uses SIPp to originate the calls. After 26 calls, the
valgrind report gives me this:

I'm interested in moving to 1.12.7 as soon as possible, but this is a
major show-stopper.
I'll be happy to provide further info. Hope this helps.
Thanks.
