malloc gives the same memory to two different nodes. How to deal with it?

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. (gdb) p tree->list $43 = (node *) 0x8be4180 (gdb) p tree->list $44 = (node *) 0x8be4180 At the...

Memory usage in Solaris - memory not freed?

Hi, I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory. I'm using "top" to get the free memory and the memory usage of processes. Thanks.

We just set up a system to use large pages. I want to know if there is a command to see how much of the memory is being used for large pages. For example if we have a system with 8GB of RAm assigned and it has been set to use 4GB for large pages is there a command to show that 4GB of the *GB is...

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
           able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
           performed.
