Re: [Users] Multiple Sockets + Multiple Processors: Any known issues?

Hi Everybody, I have some problems with a System which has several network interfaces and multiple network interfaces. The system basically receives requests on the public socket/ip and sends them, via the private socket to some proxies, which "do the work". It's a kind of load-balancer based on OpenSER 1.0.1 and the Dispatcher Module from 1.1 / CVS. Everything works fine, but sometimes i see some ICMP Messages (Destination not reachable / Port not reachable) on this "loadbalancer"; as a response to requests from the Proxies to the loadbalancer. Has anybody seen this issue before? Any ideas, what's wrong? Any known issues? Are there any known problems with multiple interfaces? Any known issues with more than one processor? I've copied my configuration below, any thing in capital letters are Parameters from my M4 file... The system is not really on high load, has 64 children and should easily handle the load... (Dual Intel Xeon(a)2.80GHz, 1 Gig of Ram) Any help would be appreciated...
