Aruba switch constant memory usage rise

Hello,

 

We have multiple Aruba switchs that seems to use more and more memory every days. We're afraid that they will crash if the memory usage reach 100% so we reboot them but since they're used 24h/24h, the customer isnt very happy about it. Is there any fix ?

 

Thank you for your help.

Re: Aruba switch constant memory usage rise

Hello, are you able to provide little bit more details (Switch models, Switch running software versions, sanitized configurations, rate of memory usage increase over time, actual memory usage seen with usual show CLI command, etc.)?

Re: Aruba switch constant memory usage rise

Hello !

 

Of course, I am eager to provide any useful information needed. The switch is a 2930M running on the ROM WC.17.02.0006. It seems that only one switch in the stack has this issue. Its memory is :  

Memory - Total   : 339,526,144

                Free   : 32,901,976

 

As for the other informations needed, can you assist me and tell me how to fetch them ?

 

Thank you for your help !

Hi,

Have you check which process use memory

# show processes sort-by memory

 

if any issue tries to update to the latest stable firmware. do you have any NMS system monitor this switch?

Re: Aruba switch constant memory usage rise

Hi! WC.17.02.0006 doesn't seem correct. Could you please verify again the software version (post the output of show flash and show version commends executed on your Aruba 2930M switch)?

Re: Aruba switch constant memory usage rise

Why do you believe the RAM used by your switch is "increasing" up to the point it will fill up? Is it an impression or have you seen a rate of increase?

Hello everyone,

 

Thank you for your help. 

 

Here are the commands you asked for :

version.PNGshow.PNG

As for the increase, I check it daily from a monitoring screen and just notice it's growing slowly. It could be an impression but I doubt it.

Re: Aruba switch constant memory usage rise

Greetings!

 

I would first recommend upgrading the stack to the latest software release (WC.16.10.0010), and see if you observe the same behavior.

 

Beyond that, when you say only one member of the stack is seeing this behavior, which member is it — the stack Commander, Standby, or one of the others?

The issue is on the stack commander.
