Hi tobi,

Thank your for your support, we are not seeing that issue in 1.3.x. It
is working fine. Is there any impact on the existing rrd files(
generated in 1.2.x) with 1.3.x.

Hi Kathirvel,

this is a problem generated by the guts of libart ... the latest
rrdtool 1.2.x versions try hard to avoid the problem but do not
allways succeed. Move to 1.3.x which uses cairo instead of libart
to solve this problem for good.
