If there are insufficient stream resources on the Unix server, modify kernel
parameters.
If an FEP is connected to too many terminals, you need to modify the Unix kernel
of the FEP to increase stream resources to avoid insufficient stream resources in
operation.
You can view system resources utilization by using the ttyd administration program
or the following command:
# netstat -m

A value of 1 for the fail column means the system stream resources are insufficient
and you need to increase stream resources by modifying the Unix server kernel.
You can follow these steps to modify system stream resources (taking SCO
OpenServer Unix 5.0x as an example):
1 Log in to the Unix server as a superuser.
2 Enter scoadmin to run SCO OpenServer Unix administration program.
3 Select [Hardware/Kernel Manager] from the main interface to enter the level 2
interface.
4 Select [Tune Parameters...] to enter the level 3 interface.
