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

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 Laura
