Streams are used by the protocol stacks and network card drivers to pass and manipulate the data being shipped between your applications (Telnet, Http, Ftp, etc.) and the network machines they're communicating with.  So I can understand shy your network interface woiuld hang when you ran out of Streams!

They are configurable in SCO by using the kernel configurator (cd /etc/conf/cf.d; ./configure).  You can see a realtime view of Streams usage at any time by typing 'netstat -m'.  This report shows one line per "Stream-Type" that is configured on your system and each line has a corresponding value that can be set with the kernel-configurator.  Pay special attention to the last column ("fail").  This tells you how many times that type of resource was requested and the request failed.  This, in itself, is not necessarily a problem as most reqeusting programs will ask for a larger resource if ti fails in obtaining the smaller-size buffer.

So, use 'netstat -m' at various times to see what types of resources are failing.  Then use 'configure' to increase these resources.  Read the man pages on configuring streams because some of these values might necessitate changes to other values.

Good luck!
