check_nt on linux host has repeated socket timeouts

Hello,

I’m trying to use check_nt to check various WMI values, however nearly every hour all the tested systems suffer socket timeouts. I have increased the timeout value to 59 seconds and still it fails. All the tested systems fail at the same time and recover at the same time. Can anyone provide some insight? Is there some problem with the linux tcp/ip stack?

Thanks!
