Hi all,

This morning our Xymon system  (Xymon 4.3.30-1.el8.terabithia on RHEL 8.6) was showing the main screens but when clicking on any status to see the data I was getting “no such host”. I restarted Xymon and it all came back but all pages completely reloaded. We’re missing RRD data for almost 24 hours.

at 08:30 yesterday we started getting the following in xymongen.log which carried on every minute until I restarted it at 08:25 this morning.
