Hi

 

The swap memory usage does not increase unless there is a specific reason.

 

I think your bigip system have some bug.

 

Open Sr and provide more detail on your bigip.

'Sr' ? Service ticket?

 

I've opened a ticket with our 3rd party and they have come back - they think its being caused by a service ( dwbld ) having an extended uptime. This then causes a memory leak. According to the documentation this should only happen if the F5 is provisioned with ASM, which it isn't.

 

Is there any other troubleshooting I can do to find out where the memory leak is ?

 

Thanks
