Hey all can you confirm the following memory issue.

Device: WS-12-250-AC

F/W: v1.4.0rc12

I ve upgraded to rc12 at April 8 and i m seeing the following mem charts.



Thank you for your time and efforts.

There was a BIG leak in v1.4.0rc13 which was never released.

Maybe there is a small leak in rc12 I do not know and Eric is off tonight playing poker tonight.

I know he fixed a BAD memory leak in rc13 which filled the memory up in about 6 hours and forced the switch to auto reboot when it reach 100% memory used which is why it was never released.

I will ping him on this so he can look into it and respond tomorrow.

I just looked at my switches running v1.4.0rc12 and they seem OK but they have only been up for 4 days so it is not real noticeable if there is a leak.

But thanks for reporting it.

The next v1.4.0rcX is due out SOON.

The memory leak was in the Ping Watch dog routine which has been completely re-written since rc12.

Do you have a ping watch dog running?

from what i can recall no i have not watch dog enabled.
I ll try to look more close on it to see if there are any clues and i ll report back.

Can you run a 'ps' command and post the output?

Sure Eric, here it is:

Looks like the problem is in discovery. I'll fix it.

I m glad that i helped you to pin point it :)
keep up the great work!

I can confirm that the latest F/W 1.4.0rc16 fixed the issue.
In the picture attached the memory usage isn't growing after the update.
Thank you Chris & Eric for fast update!
