It happens after purview has turned on. We have latest Java and 32Gb of RAM. About 100 switches are connected to Netsight.<BR /> <BR /> In log I have:<BR /> <BR /> # <BR /> # Out Of Memory: process terminated by OnOutOfMemoryError <BR /> # 18.01.2018 17:57:54,30 <BR /> # <BR /> <BR /> How is it possible? Netsight has dedicated server with 32g of RAM. Accordingly to Resource Monitor 95% of memory is free.<BR /> <BR /> 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.<BR /> Thu, 18 Jan 2018 22:07:00 GMT Ilya_Semenov 2018-01-18T22:07:00Z https://community.extremenetworks.com/t5/extremecloud-iq-site-engine/netsight-7-1-hangs-almost-immideately-after-start/m-p/41142#M5162 Hello, everybody,<BR /> <BR /> Netsight 7.1 (Windows) hangs almost immideately after start.
