Re: Two Controllers using 99% memory

Well I disagree with TAC.

 

We ran all the commands fro the cli which also reported 99% used memory. ARe you gonna tell me the cli binaries also have a display issue?

 

It's a memory leak.

Re: Two Controllers using 99% memory

I don't know which bug you could be hitting but 8.3.0.1 is old and has quite a few bugs.  One of them might be below:

I don't have time to run through those specific bugs and understand what you could be experiencing specifically, but at minimum you should upgrade because 8.3.0.1 has been discovered to have quite a few bugs being a .1 release. 

 

I really don't understand why you would also ask for help and then reject answers that you get.  It doesn't make sense...

Re: Two Controllers using 99% memory

Agree with Colin, there's no telling if what Colin is referencing is *exactly* what you hit, but early in 8.x, there were 'controls' (for lack of a better term) to reserve certain CPU proceses for X amount of CPU resources, which led to the display of higher CPU util than actual (think 'dataplane reserve 25%' even though it may have only been using 5% kind of thing.

 

So specific to OP, we won't know what the actual issue was, but that WAS one thing that was in some early code that has since been addressed.

Re: Two Controllers using 99% memory

memory on two controllers was using 99%.

 

I rebooted both controllers.

Memory immediatelly  was at and is still currently at about 49-50%.

 

Are you saying that this is cosmetic according to the bug you posted?

 

That bug specifically relates to the "mem available" column being omitted from the cli. That has nothing to do with the controllers exhausting all memory. I reject answers that don't make any sense.

Re: Two Controllers using 99% memory

I only showed you the bug(s)  to demonstrate to you that yes, counters that relate to memory and CPU can be wrong.

 

You are free to think what you like.
