Some use tcp, some udp. I have Linux and FreeBSD clients running. The build system runs on Linux. All Linux's are UDP.... Also connect the build machine to the old 7.2/amd64/bge0/ufs machine, but there the count doesn't go over a few 1000 mbufs. > It did not help.

'mmmm, I did set the zvol version this morning also to 14 but I think that I ran into trouble already when still running version 13. And the server was used as storage for the build system since the last 2 weeks. Uptil yesterday without much trouble. --WjW
