My test case is to have 6 processes each create 5000 TCP IPv4 connections to each other on a system with 16GB RAM and send slow-speed data. This works fine on a 4.7 kernel, but will not work at all on a 4.13. The 4.13 first complains about running out of tcp memory, but even after forcing those values higher, the max connections we can get is around 15k.
Both kernels have my out-of-tree patches applied, so it is possible it is my fault at this point. Any suggestions as to what this might be caused by, or if it is fixed in more recent kernels? I will start bisecting in the meantime... Thanks, Ben -- Ben Greear <gree...@candelatech.com> Candela Technologies Inc http://www.candelatech.com
