NLB Load Balanced Servers Constantly Restarting

I am having an issue on one of two NLB load balanced servers. The server having issues looks to be constantly restarting (either the site, or the app pool); see the trace below.

Any ideas what could be causing this? All back-end accounts are offline, so nobody is making configuration changes through the dashboard. Operations staff are not changing the web.config, as verified by timestamp and content.

Is this possibly a max # of connections issue? If so, what specifically am I looking for?

 i am having this same problem, is there any resolution to this?

 

Hi Pierre,

As we could not faced such issue before, could you please open a support ticket and provide us with the log files.

Please remove all the files under: <your project>\App_Data\Sitefinity\Logs. Once the issue is reproduced again, send us all the files generated in that folder.

Regards,
