Netsight/EMC - high memory consumption

Userlevel 2

we currently have a EMC running with the "medium" size (2*8 Cores, 32 GiB RAM & 480 GiB Disk), we manage ~350 Switches and a few WLAN controller and NAC appliances with EMC, as well as ~400 APs.

From time to time the memory rises up to more than 32 GiB, so that the swap is used and the system is extremely slow - after a reboot everything is fine.

Has anyone experience with such issues?

Best Regards
