Kernel 2.4.19 glibc 2.2.5
I am running a parallel program on 170 nodes, with 2 processes on each nodes. so 340 total processes. Each process has a TCP connection established with every other process. So each process has 339 sockets in ESTABLISHED state. The problem occurs when I try to write() on these socket. The TCP connection gets dropped for some of the sockets of a few processes as soon as they try to write to those socket. This problem, however, does not occur, if I reduce the number of processes to less than 306 (305 TCP sockets/connections for each process).
Any ideas why connections are getting dropped?
