Shalom,

Whats the OS.

This output doesn't look like any HP-UX machine I have around here. We have nearly 100.

Let's start with the shell since a normal shell has ulimit as a builtin. What do the commands:

type ulimit
echo $SHELL

report? The header and the capitalization is definitely not from a Bourne, POSIX, or Korn shell.

Hi,

The shell is ksh.

The output is collected from on of our tools, so you see the capitalisation. we get the entire system environment from the same.

Since your example is from your special tools, we can't provide much help. From ksh, just type the command:

ulimit -a

and post those results. From your question:

> can it be a -ve value?

I am assuming that you are questioning the negative value for DATA, and no, ulimit will not report a negative value. Most likely your tools may have made a calculation and signed integer overflow has occurred. This is a programming error. If ulimit reports a negative value, you are likely not up to date on patches.

Bill,

Our application, just executes the command on the machine and captures the output, so it guess there is no calculations going on there. its been working fine for other HP machines.

Since the issue is on this particular machine we are wondering if it might be because of the ulimit (data) value.

Thanks for your time.

What does ulimit -a by itself report? Run the command using the POSIX shell since ulimit is a shell built-in. If there is a difference, the shells probably patches.

The value you have is most likely: 4160684032

>just executes the command on the machine and captures the output, so it guess there is no calculations going on there.

Captures it how? As a string, or do you convert it to an long/int? This would be your problem as Bill says.
