Sorry for double posting ! I didn’t realize i was on the wrong lane.
When sending data from different threads on different datagram sockets i get an ENOBUFS 255 /* No buffer space available */
after some time. Using a single thread on a single socket works ok.
The application is videostreaming, the datarate is high, 90 Mbit / 500Mbit per sec on FastE / GigE Hardware.
I’m running QNX6.4.1 and Intel Pro100 / Pro1000 Cards.
I increased the net.inet.udp.sendspace as much as i could with sysctl to 188000.
Anybody came across this or has any idea?
