Hello Mike

Thanks for your answer. I tried with '-t u1' and I get the same error.
I also tried to run -mp 1024 and I added net.ipv4.ip_local_port_range
= 1024 65000 to /etc/sysctl.conf, and then sysctl -p /etc/sysctl.conf.
In my xml I use [auto_media_port], which now starts from 1024 and I
should have enough ports.

This still did not fix the problem.




You can run sipp under strace and find out which particular syscall fails.
Just run strace -ff -o strace.log sipp ...
Where ... should be replaced with sipp args.
Then read and analyze the strace log files.


I would also try to increase the number of open file descriptors per process. Like this ulimit -n <some big number>.

HTH, Dmitry
