Hi All,
I have a WS-C2960-48PST-L (15.0(2)SE4) which is working fine on the surface but SolarWinds is reporting that the memory usage has been at 80% for a long period of time.
Using all of the memory commands I can see that there are a lot of dead processes.

Hello,
this is often related to buggy software. Try and upgrade to 15.0.2-SE11...

As mentioned other poster, 15.0(X) some version have bugs, do you have any SNMP polling frequenty, worth checking disable and see if that improves.
Not sure may be bug :

Hi @Georg Pauwen thanks for the quick suggestion.
I have the updated software to try but last time I did this I encountered an issue with not enough free storage space.
Last time I unticked the option to backup existing firmware image but the whole switch crashed and I ended up swapping it out with another device (this one) both of them have the same firmware but also the same 80% usage issue.

Hello,
that doesn't sound good, you don't want to have to replace the entire switch...
Check if your switch supports the global command below:
no macro auto monitor
If so, configure that and monitor if that changes the memory usage...
