Hi,
Which opensaf release you are using ?
Which transport you are using TCP or TIPC ?
In the recent Opnesaf releases, their is no limits for data.
I hope you are using TCP transport , give a try by changing
system send/receive buffer
For example : add following to temporally increase send & receive
buff size in start() of /etc/init.d/opensafd
start() {
sysctl -w net.core.wmem_max=13107100
sysctl -w net.core.rmem_max=13107100
sysctl -w net.ipv4.tcp_rmem="4096 87380 13107100"
sysctl -w net.ipv4.tcp_wmem="4096 87380 13107100"
