[Users] rtpproxy CPU usage issue..

Hi, Have any of you folks seen an abnormal CPU usage issue with rtpprpxy? At times, "top" shows rtpproxy uses 100% CPU (sometimes 99%, sometimes even 101%!), and it stops responding to openser. I have to restart everything now. A small thread in Serdev list recommends upgrading rtpproxy to latest in CVS: http://lists.iptel.org/pipermail/serdev/2006-June/007459.html Mine was fairly old, so I upgraded, but without much progress. What really bugs is I don't know what triggers it. Backtraces suggest that this occurs in different places in rtpproxy, before and after upgrading. Before upgrade: (gdb) where #0 0xb7f49410 in ?? () #1 0xbffd6d88 in ?? () #2 0x00000076 in ?? () #3 0xbffd2410 in ?? () #4 0x4a8d9fd1 in sendto () from /lib/tls/libc.so.6 #5 0x0804ac0c in main (argc=7, argv=0xbffd6e14) at main.c:1467 After upgrade: (gdb) where #0 0xb7f0a410 in ?? () #1 0xbfcb0258 in ?? () #2 0xbfcadfc0 in ?? () #3 0xbfcab8e0 in ?? () #4 0x00bb8dd1 in recvfrom () from /lib/tls/libc.so.6 #5 0x0804a568 in main (argc=7, argv=0xbfcb02e4) at main.c:1364 Any clues? Is this a known problem and is there a patch or some sort ofworkaround? Is there anything I need to upgrade? (This is CentOS 4.4, FWIW) Anything that should be done in openser configuration? Thanks much in advance. - Sajith.
