[Users] mediaproxy problem

Hi! I'm having problems with the mediaproxy which I can not resolve. Sometimes, when the session is terminated, mediaproxy does really terminate the session and the ports keep allocated. At the moment I'm having 400 open sessions and mediaproxy uses 80% of the CPU. Attached you can see the logfile of mediaproxy (to avoid line breaks). The first call does not terminate correctly and the ports are still opened. The second call terminates correctly. Can someone help me digging into this problem? regards klaus Dec 2 10:30:49 philipp mediaproxy[440]: command request 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167 1.2.32.167:19514:audio 1.2.32.167 1.2.32.167 remote 3.4.240.143 remote Cisco-SIPGateway/IOS-12.x info=from:06503836629@1.2.32.167,to:43159966509977@1.2.32.160,fromtag:16588354-2D7,totag: Dec 2 10:30:49 philipp mediaproxy[440]: session 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167: started. listening on 1.2.32.83:36888 Dec 2 10:30:49 philipp mediaproxy[440]: command execution time: 1.33 ms Dec 2 10:30:57 philipp mediaproxy[440]: command lookup 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167 3.4.240.143:16434:audio 3.4.240.143 1.2.32.167 remote 1.2.32.160 unknown Linksys/PAP2-2.0.13(LSb) info=from:06503836629@1.2.32.167,to:43159966509977@1.2.32.160,fromtag:16588354-2D7,totag:df301db23bf537dbi0 Dec 2 10:30:57 philipp mediaproxy[440]: command execution time: 0.73 ms Dec 2 10:30:57 philipp mediaproxy[440]: session 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167: called signed in from 3.4.240.143:16434 (RTP) (will return to 3.4.240.143:16434) Dec 2 10:30:57 philipp mediaproxy[440]: session 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167: caller signed in from 1.2.32.167:19514 (RTP) (will return to 1.2.32.167:19514) Dec 2 10:31:01 philipp mediaproxy[440]: session 28667818-624D11DA-A322FFDE-5D565222(a)1.2.32.167: caller signed in from 1.2.32.167:19515 (RTCP) (will return to 1.2.32.167:19515) Dec 2 10:33:22 philipp mediaproxy[440]: command delete BF809954A357C8D45FCF51D81299(a)84.151.154.100 info= Dec 2 10:33:22 philipp mediaproxy[440]: command execution time: 0.27 ms Dec 2 10:36:54 philipp mediaproxy[440]: command request 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167 1.2.32.167:18412:audio 1.2.32.167 1.2.32.167 remote 1.2.33.19 remote Cisco-SIPGateway/IOS-12.x info=from:069911160036@1.2.32.167,to:4359966366102@1.2.32.160,fromtag:165E1650-2D0,totag: Dec 2 10:36:54 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: started. listening on 1.2.32.83:36894 Dec 2 10:36:54 philipp mediaproxy[440]: command execution time: 1.52 ms Dec 2 10:36:57 philipp mediaproxy[440]: command lookup 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167 1.2.33.19:32240:audio 1.2.33.19 1.2.32.167 remote 1.2.32.160 unknown CSCO/6 info=from:069911160036@1.2.32.167,to:4359966366102@1.2.32.160,fromtag:165E1650-2D0,totag:000dedfb04cc2d723b9fccb6-64a00b22 Dec 2 10:36:57 philipp mediaproxy[440]: command execution time: 0.60 ms Dec 2 10:36:58 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: caller signed in from 1.2.32.167:18412 (RTP) (will return to 1.2.32.167:18412) Dec 2 10:36:58 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: called signed in from 1.2.33.19:32240 (RTP) (will return to 1.2.33.19:32240) Dec 2 10:37:01 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: caller signed in from 1.2.32.167:18413 (RTCP) (will return to 1.2.32.167:18413) Dec 2 10:37:08 philipp mediaproxy[440]: command delete 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167 info= Dec 2 10:37:08 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: 510/505/1015 packets, 30800/30300/61100 bytes (caller/called/relayed) Dec 2 10:37:08 philipp mediaproxy[440]: session 224B803-624E11DA-A32BFFDE-5D565222(a)1.2.32.167: ended.
