ExtremeXOS provides memory management capabilities. Each process in ExtremeXOS runs in a protected memory space. This infrastructure prevents one process from overwriting or corrupting the memory space of another process. For example, if one process experiences a loop condition, is under some type of attack, or is experiencing some type of problem, that process cannot take over or overwrite another processes' memory space.
Memory protection increases the robustness of the system. By isolating and having separate memory space for each individual process, you can more easily identify the process or processes that experience a problem.
To display the current system memory and that of the specified process, use the following command: show memory process name {slot slotid}
You can also use the show memory {slot slotid} command to view the system memory and the memory used by the individual processes, even for all processes on all MSMs/MMs installed in modular switches. The slot parameter is available only on modular switches and SummitStack.
In general, the free memory count for a switch decreases when one or more running processes experiences an increase in memory usage. If you have not made any system configuration changes, and you observe a continued decrease in free memory, this might indicate a memory leak.
The information from these commands may be useful for your technical support representative if you experience a problem.
The following is sample truncated output from an ExtremeSwitching switch:
