[rrd-users] RRD error at DST shift on sparc Solaris?

Dear RRD users,


I am using RRD, 1.2.19, to store utilization metrics for a number of
servers all running sparc Solaris. Polling processes store the values
and independently a threshold monitor tests the limits and raises an
SNMP trap when appropriate. There is also a process that fetches 24 hour
snapshots of the data and archives them to flat files. Everything is
using epoch time.


Last weekend when the DST time shift took place, the threshold monitor
process for every DS raised a trap because the query to RRD failed. I
have also had a problem last spring where the timestamp was garbled for
the interval where the DST time shift happened.


Has anyone else seen this behavior?
