Just forwarding this changelog from yesterday. xcs now uses Unix domain sockets in unstable. This was a hot thread a couple months back with strong opinions on both sides and no clear resolution on the list, so I thought some people might like to know the developers'' resolution. This should be good news for those seeking tighter dom0''s, particularly those who

...running on Red Hat 9.I am running the test kit for 100 warehouses with tpw(terminal per warehouse) value of 80.

The particular point where error comes looks like this- so_socket(PF_INET, SOCK_STREAM, -4, "", SOV_DEFAULT) Err#120 EPROTONOSUP . Above this error the normal behaviour was: so_socket(PF_INET, SOCK_STREAM, IPPROTO_TCP, "", SOV_DEFAULT) = 255 I found that this error comes when the protocol is not supported by the addres family.
