first problems with QNX 6.3.0 SP3

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).

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.
