SIOCGI FALL Out of stream resources 1

[newsdata]

Changed the ip address on our SCO system and now out of stream resources.

How do you increase the stream resources?

Thanks in advance

If OSR 5.0.x:
scoadmin -> Hardware/Kernel
Tune Parameters
12. Streams
The NSTREAM value will impact the Class* values.
You have to increase the NSTRPAGES value too.

In what increments should I increase these values?

current setting:

NSTREAN 6144
NSTRPAGES 1024

 

[PHV]

This depends on the values returned by netstat -m

I had increased the NSTREAMS and NSTRPAGES. The system locked up again. the netstat -m shows failures for classes 2 through 6, the fails displayed on the far right column.

class 2, 128 bytes 2936 2936 0 28262 2939 576
class 3, 256 bytes 4 4 0 87865 168 413
class 4, 512 bytes 0 0 0 785 9 1760
class 5, 1024 bytes 0 0 0 367 1 94
class 6, 2048 bytes 1798 1798 0 9856 1798 4012

total configured streams memory: 4096.00KB
streams memory in use: 4177.63KB
maximum streams memory used: 4229.57KB

Which values represent the classes in the kernel mgr. so that I may increase the values?

The NSTREAM value will impact the Class* values.
You have to increase the NSTRPAGES value too.
BTW is your SCO box a samba server too ?

No, the SCO box is not a samba server.

Thank you.

You've been very helpful!!!

I've been increasing the NSTREAMS and NTRPAGES and still running out of steams. I have to reboot everyday. Is there anything else that could be causing this. This issue began after changing the ip address and subnet.

here is a capture of netstat -m:
