Hello,

I started SER performance test with sipp traffic generator on FreeBSD 5.3. After starting 300 calls per second I got the following error:

Mar 14 16:35:09 devel ser[1506]: msg_send: ERROR: udp_send failed
Mar 14 16:35:09 devel ser[1506]: ERROR: udp_send: sendto(sock,0x2a258ae0,568,0,0x286be26c,16): No buffer space available(55)

SER send "503" the service not available. I don't use mediaproxy/rtpproxy to exclude problems there.

Could someone help me with this?

Thank you,

Tina
