One of my F5 Big-IP had problem while resolving DNS, I wonder if the uptime of F5 is the cause?
Can you please suggest me the "best practise" uptime to Schedule reboot F5 device?
My F5 is 1716 days uptime now, is it too high?
Thank you and best regards!
As far as I know, there's no best practise for uptime, it should be working just fine without any reboots.
To investigate what may be the cause though, have you tried running a qkview and analyzing is using iHealth? It should highlight any major problems in the system.
If unsure on how to do this, in the GUI, go to System - Support and then create a Snapshot. Once finished, go to ihealth.f5.com and upload the file there.

Hope this helps.
