Rrdtool trap divide error

[twiceborned]

One moment cacti stopped showing any graphs.
I know that poller do collect information(with the help of TCPdump), but most of that information goes nowhere - only 10% of .rrd files are updated on each poller cycle and because of this graphs, ofc, can't be made.
In /var/log/messages there is
traps: rrdtool[8936] trap divide error ip:7f95c948257f sp:7ffe19ea48c0 error:0 in librrd.so.8.0.0[7f95c9446000+4e000]
error
cacti and cacti-spine versions are 0.8.8h and I know they are kinda too old, but I don't know if this bug is related to this. Probably not, I think.
Did someone encounter something like this? And how can I test it to find more information?
