Checking memory resources

Use the methods in this section to check memory resources.

Use any of several UNIX commands to obtain total and available memory information. For example:

• vmstat

• dmesg, top, pmap (Sun Solaris)

• glance (HP-UX)

• lsps, bootinfo, lsdev (IBM AIX)

See your operating system documentation for commands specific to your platform.

To check memory statistics:

1. Right-click an empty space on the Windows taskbar, then click Task Manager to open the Windows Task Manager.

2. Click the Performance tab.

Some platforms may also limit the maximum amount of memory a process can use, regardless of the amount of memory available on the system, or place limits on the number of file descriptors, mutex, and threads that a process can create. See your operating system documentation for the specific commands to set these limits on your platform.

These types of errors are fatal and usually cause the OpenSwitch server or coordination module to shut down. Even if the process continues to run, you should:

1. Shut down the OpenSwitch server or coordination module if possible without disrupting work.

2. Check the available resources.

3. Restart the OpenSwitch server or coordination module when more resources are available.

See the OpenSwitch Installation Guide for your platform for system requirements. See Chapter 4, “Starting and Stopping OpenSwitch and RCMs,” in the OpenSwitch Administration Guide for instructions on starting and stopping OpenSwitch servers and CMs.
