rrdcached errors

[rajasegar]

I am getting all theser errors related to rrdcached in the /var/log/messages

1) Can these logs be redirected to its own log file?
2) Why is these errors coming out? I deleted the .xml and rrd files but it keeps on coming back.

Check your system time. If NTP pushes the time back by a couple of seconds, you may see this issue. Additionally, if you have more than 1 check configured that writes to the same RRD, you may experience this error as well. What is the output of the following commands?
