As part of monitoring NTP offset from sync'd host we scheduled a ntpqexe. The problem started after 4-5 days, the memory utilisation had increased to significant level >80%. On analysis we found it was a gradual increase and using RAMMAP we saw every time the ntpq.exe will run it will leave behind 24k of memory in PAGE Table with 0 B in Private. Moreover this issue is specific to windows server 2019 we tried following same steps on windows server 2012 machine and it worked perfectly fine with no memory creeping issues.
