Thanks a lot for the help. It gave me a start (keywords for googling )...given below is the code for filling the memory in linux ....yes the swap is unavailable. The vendor installed it that way.

When allocating memory for two different nodes, the resulting memory are the same. Clearly, this will lead to a mistake. This happened in a function. And the process must be in a function.

$43 = (node *) 0x8be4180

$44 = (node *) 0x8be4180

So far I have found a script that's good for CPU usage but it does nothing for memory. I have also tried the application called 'stress'... (0 Replies)
Actually for a process to run it needs text, stack , heap and data segments. All these find a place in the physical memory.
Out of these 4 only heap does exist after the termination of the process that created it. I want to know the exact reason why this happens. Also why the other process need to... (20 Replies)

2. .dat files are huge text files and .txt files contain some important words.
3. I am just doing strstr to find the patterns.
4. The function returns the... (3 Replies)

Hi all, bit of a forum newb here, so apologies if this has been covered else where, but I wonder if any of you has any experience with stress testing servers, specifically using 3rd party services. We run a very busy production system, and just haven't been able to simulate the user activity while... (1 Reply)
