Title: ntp Questions
Post by: bimmerdriver on December 15, 2018, 06:16:50 pm

I have two opnsense systems, both running on windows server 2012r2 hyper-v. One system is running the latest release and the other is running 19.1b. I've noticed on both systems that the ntp service is taking longer to start up after rebooting than it used to. Both systems are using the default ntp settings.

I took a look at the status and I have some questions.

Here are the messages in the log, beginning after restarting the ntp service:

One of the message refers to memory. The system is currently using only 20% of memory.

Also, it appears that one of the default servers is not reachable. Refer to the screen capture.

Hi bimmerdriver,

When looking at your screenshot, I noticed that it was only the IPv6 address that was having an issue.  How is your network infrastructure setup?  Can you use an IPv4 address instead?

Regarding the memory lock error: Dec 15 09:13:09   ntpd[84257]: mlockall(): Cannot allocate memory

I was referred to this 2017 October 21 by @lattera (Shawn Webb) and @mjharmon: https://mobile.twitter.com/lattera/status/921787114580213761

these are standard messages.
The opnsense gui shows the servertime and the sync source under dashboard\lobby in the section network time.

for me to work correctly, i had to set kern.timecounter.hardware in the system\settings\tunables
i have set the value to "HPET"
