I am doing some end to end testing using SIPP on RHEL 4.2. Both my client and server machiens are running RHEL 4.2.
When I try to issue the command :
sipp -t tn -sn uac <server_vip> -i <client_ip> -m 10
on the client and :
sipp -t tn -sn uas -i 0.0.0.0 -m 10
on the server, all works well ,ie, TCP SIP works fine on port 5060. However, as soon as I remove the -t tn flag and switch to UDP, the server core dumps and produces something like this :
Warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE = 1024

I am running sipp-3.3. I am unsure what to make of this. By the way, my netstat shows that my server is listening to port 5060 for both tcp and udp traffic, so that rules out one problem!
Any suggestions?
