Re: about the maximum connection number of gnuGK(H.460.18/19 enabled)

Hello Jan,

Thanks for the reply! yes I reset the open files and other parameters
of my linux_PC, and until now I already can do 210 concurrent calls,
Thanks!

Regards,
Bo Xu


Hi,

GnuGk doesn't have a built-in limit. Check your trace file, you'll
probably see errors indicating insufficient sockets or file handles.
If you use Linux, ulimit -n is your friend.

Regards,
Jan
