Daily restart f5 device

i think it is not normal that memory used is not decreased when number of users is reduced. shouldn't you open a support case to check?

Hi nitass,

Not you mentioned. The problem was the memory usage getting increasing with out the device restarting for couple of days. Not due to user increasing / decreasing.

Please advice on this case.

Certain versions have had memory leaks in usage. Check with tmstat what's using the memory. Also upload a qkview to iHealth. It'll generally identify where you're vulnerable to bugs and advise what version you need to fix them.

memory leakage issues are seldom openly published by F5 (SOL in AskF5) and I believe it won't show either in iHealth (but anyway worth a try of course).

Do you see similar LTM log entries?

tmm1[11298]: 011e0003:4: Aggressive mode sweeper: 1 Connections killed
tmm1[11298]: 011e0002:4: sweeper_update: aggressive mode deactivated. (424058/500224 pages)

What effect do you have on user's connections when high memory usage?

running "tmctl -a" and looking at the tmm.pagemem section, what are the value you get (when high mem)?

I think you'll find that iHealth does indeed tell you if you're susceptible to any known bugs that cause memory leaks. It wouldn't be a very good tool if it didn't...

are you able to determine what process is using such high memory?

tmsh show sys memory

also, as Nitass mentioned earlier, you should open a support case as your high memory consumption might be an already-known issue.
