System Time Offset Growing Exponentially for 1 Server

Troubleshooting
1

Hello,

i have this strange phenomenon where the System Time for 1 single Server keeps growing exponentially in the Service (and RRDs) but the time itself on the Server is just fine and only seconds apart from others.

Systemtime of the Trouble Server :
vcenter(via vsphere Agent, has worked flawlessly so far):ntpoffset
cmk -d from Host, Systemtime = 1597925162
from another Server : cmk -d from Host, Systemtime = 1597925629

The PDC for Time is the same as for the CMK Slave on this Location. It was working fine for a couple months and then suddenly it started to just add up the Offset ontop of each other instead of refreshing it. Only Happening for this one Server though. CMK_Raw 1.6.p3

I’ve checked all the Settings and everything seems fine and this feels like it’s Happening for no reason, since the Server has been monitored for a couple months already.

Any advice would be greatly appreciated.

Solved the Problem :
Somehow CMK couldn’t update the Cached Agentoutput anymore so the file in /omd/sites/<siteID>/tmp/check_mk/cache/HOSTNAME wasn’t being updated anymore but was still being referenced all the time which is why the Offset just keeps growing, obviously. So removing the file solved the problem.
