Hi Eman, You probably should check linux open files limit for client and server process, because each new connection counts to this limit.
Some basic info could be found here: https://www.networkworld.com/article/2693414/operating-systems/setting-limits-with-ulimit.html Also you can attach to process with strace utility and look for connect syscall (it would get an error in case of hitting open file limit). Also: why should you use so many connections at once?
