[sr-dev] No memory left in send_subscribe (PUA) from update_pua while building the tm dlg_t structure

[laura testi]

Hi,
we are using the PUA_XMPP and PUA modules from the master branch. When
the modules are started, everything are ok, the presence events from
XMPP are sent to kamailio SIP servers (PUBLISH/SUBSCRIBE) and cached
in the hash. But when there are several thousands records in the hash
tabel, the update_pua function called in the hashT_clean gives a lot
of "No memory left" error when the hashT_clean is waked up from the
time:

ERROR: pua [send_subscribe.c]: No memory left
ERROR: pua [pua.c]: while building tm dlg_t structure

The failed call is:
	td = (dlg_t*)pkg_malloc(size);
	if(td == NULL)
	{
		LM_ERR("No memory left\n");
		return NULL;
	}

in dlg_t* pua_build_dlg_t(ua_pres_t* presentity) function in
send_subscribe.c. The size is about 400 and something... It's
strange.....

Is it the memory leak in the PUA module?



I also try to increase the pkg_memory from 4MB default to 16MB, but it
doesn't help.


Any Idea?

Thanks in advanced
