Hello Everyone,
My device info is :-
Device:-j4350
Junos :- 9.2R1.10
Yeah Yeah i know Old Software :P
I just want to know if my memory utilization is normal or not.
Memory Utilization:-

I believe that it's fine, I checked a few of our Juniper Routers and all are over 60% memory use with no issues.
Would be interested to see if it does drop down after a reboot though as it has been online for over 900 days, also it may be worth checking your logs to see if there is any mention of memory issues just to be on the safe side. -

Thanks Wiz ,
Well i have not found anything regarding memory in logs, the device has constant 60% memory utilization from the start without any fluctuations.
