[Xymon] gaps in gaps after server upgrade to Xymon 4.3.18

[Nicole Beck]

Hello,

I recently upgraded my xymon servers (primary and failover) from Xymon 4.2.3 to 4.3.18. After the upgrade, we noticed gaps in such as CPU Utilization, TCP/IP Statistics, and Block IO, but only for clients that are running the xymon 4.2.3 client, not for those running the Big Brother client. I built a new 4.3.18 client but we still see gaps.


We are running the old vmstat-bf.sh and netstat-bf.sh extension scripts in the xymon client.


I turned on debugging for rrdstatus and rrddata on our failover server, and saw errors such as the ones below during the times when there was a gap.


Does anyone have ideas on how to troubleshoot and fix this? Why was the xymon client working ok with xymon server 4.2.3 and not 4.3.18?
