Non Responsive Cisco ISE

[mpbaker82]

I have two vm cisco ise boxes (2.4, patch 3) that im trying to bring up in a distributed environment. The primary box is up, configured, working great and set as primary admin node. I've done countless hours of testing, configuration, etc. 

I go into VMware, start my ISE application, and after about 10 min's all the processes are running and everything looks perfect. I can access both boxes via the GUI and CLI.

Four or so hours go by...

I log back into the laptop, open my browser (firefox or chrome) and navigate to the ISE GUI. The session times out for both boxes. I then proceed to start putty and CLI into both boxes to check some logs. Im prompted for the username, but when i hit "enter/return",  it just becomes unresponsive. I loose complete access to the box (GUI or CLI) unless i bounce the VMs. 

Im not getting any error messages, prompts, or warnings to post.

Thanks in advance for any light you can maybe shed on this issue.

Make sure you don’t have any backups or snapshots via vmware going as these can halt a system

Validate correct resource availability per admin guide vmware resources around ram and cpu

Otherwise would recommend working through tac

Thank you Jason, it was def the snap shots. our EVT team does then nightly. A simple power off and back on resolves the issue... at least till the next snapshot. :)
