Cannot create pipe

Hi,

I'm new here, so please dont shoot me if I forgot something Smilie
Some SCO box we've (our company) got recently from a new customer runs an app that hangs the entire box every once in a while.
Today when an admin tried to start the db we got this error:
$ dbstart
dbstart: line 22: cannot create pipe [Out of stream resources]

Im pretty familiar with FreeBSD, but quite the noob with SCO, so what and where should I edit files in order to allow more resources to be used?
Or is this a (virtual) memory problem?

Regards,

Niels

Run scoadmin, and select "hardware/kernel manager" then adjust Streams parameters (option 20), relink the kernel and reboot.
Assuming you are using Openserver 5.0.x or 6.0
On older releases 3.2.4 run sysadm.

Relink?

Thx for the response!

Do you have a link for the 'relink the kernel' part?
Or is it that simpel that you can explain it in a simple reply? Smilie

Relink is part of the menu structure of scoadmin->hardware/kernel.

Answer yes to make this the default kernel, and yes to rebuild environment.
If after you have done this and rebooted, and are not happy, reboot and enter "unix.old" at the boot prompt.
You can probably double the default parameters.

Documentation is at The SCO Group, Inc. | Support | Docs | Documentation

All versions of 5.0.x are essentially the same.

It's Unixware 7, Release 7.1.1.
Does that make a difference?
I found the manuals for it on The SCO Group, Inc. | Support | Docs | Documentation | UnixWare, but scoadmin wise?

Monitoring and tuning the system

Values and parameter names look the same, but I am sure that the user interface is quite different. Guess you have some reading to do.
