Do the following to increase TCP performance:
1- Increase the number of available local ports:
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range
2- Increase the amount of memory associated with socket buffers (socket input and output queues):
For input queues:
echo 262143 > /proc/sys/net/core/rmem_max
echo 262143 > /proc/sys/net/core/rmem_default
And wmem_max , wmem_default for output queues.
3- TCP stack
echo 0 > /proc/sys/net/ipv4/tcp_sack
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
4- opensips memory pool is well configured : http://www.opensips.org/Resources/DocsTsMem

Hi Binan,
Thank's to Bogdan's patch I was able to run opensips 1.8.1. However, the problem with TCP under highload is still present.
Do you have any other ideas?
Thanks
Diego
