Esix problem

[Larry Foard]

I have been having a very weird problem with an esix database I am writting.
Once I get around 14 connections to the database, I am unable to connect
any more and weird things start happening. Once I reach the limit I can't
run any programs (getting either a Killed responce from the shell or an
out of memory). The number of jobs running is no where close to NPROC, and
there appears to be more than enough swap space left. I have tried adjusting
the STREAMS parameteres and there seems to be no effect. 
The database requires a large number of TCP/IP connections, netstat shows
around 60 when I can no longer accept connections. The database itself
consists of a central server that handles requests for records, there is
a second process that forks when it recieves a connection (from a PC
using ethernet or a local terminal program), this second process also
connects to the main server. 
Any ideas what limit I am exceeding?
