first problems with QNX 6.3.0 SP3

Postby jalonso » Wed Feb 28, 2007 10:56 am

Hello,

I have just intalled QNX 6.3.0 SP3 in a machine, and I have 2 problems
that I can´t solve.

My first and important problem has to do with a ramdomly freeze of the
operating system. I start QNX, I can work properly (there is no problem
or I can´t see any problem at least). But some time later (a ramdom
time), QNX is frozen. I don´t know what happen because I can´t use
keyboard, mouse, .... I suppose that two things can produce the problem
(100 % of CPU time is busy):
- a hardware interrupt that is constantly ask for time
- a high priority thread that runs without control.

How can I identify the problem? and how can I solve this problem? Is
there any bug in this QNX version? I don´t think so, but...

The second problem is about qnet. I have installed in other machine QNX
6.2.1A, and I can´t see it from my new QNX 6.3.0 SP3. Is there qnet
compatibility from QNX 6.2.1A to 6.3.0 SP3? or Do I need to indicate to
qnet that I want to see other QNX version with some param?

Thanks in advance.

Jorge.

Hello,
you must use qnet-compat
#mount -T io-net qnet-compat.so

You can try the "hogs" utility. It loops and lists the processes that
are using the CPU. For example, run this in an extra window:

hogs -n -%5

The -n option says to disply the process name, and the -% option specifies
the minimum CPU usage to display (which lets you omit processes that are
idle or using small amounts of CPUtime).

The second problem is about qnet. I have installed in other machine QNX
6.2.1A, and I can't see it from my new QNX 6.3.0 SP3. Is there qnet
compatibility from QNX 6.2.1A to 6.3.0 SP3? or Do I need to indicate to

As someone else mentioned, you need to use npm-qnet_compat.so (make
npm-qnet.so a symlink to it).

Hello,

There is no problem using npm-qnet_compat.so, as you said.

Thank you very much.
