[Serusers] Mediaproxy consuming RAM resources.

Hello list. I was looking the process in my SER sip-proxy with the mediaproxy running. Every time i look, the percetage of used RAM is increasing. It seems like for some reason mediaproxy is not releasing the resources used in RAM. You can look this in the next lines : PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 1952 root 15 0 284M 266M 1628 S 0.0 26.4 19:22 0 mediaproxy.py Can someone tell me if this is a bug of mediaproxy or maybe a missconfiguration in my ser.cfg? I want to ask a question regarding to tear down sessions with mediaproxy also. In my ser.cfg i have : if (loose_route()) { if (method=="BYE" || method=="CANCEL") { log(1, "NAT: BYE o CANCEL recibido --> terminando la sesion de media\n"); end_media_session(); setflag(1); }; t_relay(); break; }; Is this ok? I think in some cases (i'm still unable to determine which ones), SER does not tear down a mediaproxy session. You can see for example this two session, both of them were ended, but it seems to be active even before that. (i ommited the source, via and destination IP's in the output of the session.py) Status Duration Codec Type Traffic ---------------------------------------------------------------------------- --- hold (2430) 40'40" G729 Audio 11.53k/29.58k/18.45k inactive 0'02" Unknown Audio 0/0/0 Can someone tell me what's happening? I'm runnig : [root mediaproxy]# ./mediaproxy.py --version mediaproxy.py 1.0 Thanks in advance. Regards, Ricardo M.
