Netsight 7.1 hangs almost immideately after start


Userlevel 4
Hello, everybody,

Netsight 7.1 (Windows) hangs almost immideately after start. It happens after purview has turned on. We have latest Java and 32Gb of RAM. About 100 switches are connected to Netsight.

In log I have:

#
# Out Of Memory: process terminated by OnOutOfMemoryError
# 18.01.2018 17:57:54,30
#

How is it possible? Netsight has dedicated server with 32g of RAM. Accordingly to Resource Monitor 95% of memory is free.

Here is full log of Netsight (below). Initially Netsight was installed with 4G or ram, then I've increased ram for this virtual machine to 32Gb.

There really indicates what is going on.

For improved performance, it needs to be customized.The default memory setting for a 64 bit NetSight server is at least -Xmx2048m.This can be increased by stopping the server and editing the C:\Program Files\Extreme Networks\NetSight\services\nsserver.cfg.This file defines memory values for the operation of the NetSight server.Note: Use caution when changing these values.

I would use these values as guidance, even though they are for 8.x, they give more 'headroom' for the processes.https://gtacknowledge.extremenetworks.com/articles/Solution/EMC-memory-settings
