Rrd file Incompatibility issue between 1.4.2 and 1.3.9**

[human]

I have upgraded RRDtool to version 1.4.2. I previously used RRDtool 1.3.9*. After RRDtool 1.4.2 installed , some of the rrd files generated by version 1.3.9 failed to update and I got error logs in /var/log/message as follows:

Aug 24 14:46:33 BJATCA24stb1 rrdcached[7964]: queue_thread_main: rrd_update_r (/var/lib/ganglia/rrds/SummaryInfo/SCTP@sctp_obs@STATION_I@…) failed with status -1. (/var/lib/ganglia/rrds/SummaryInfo/SCTP@sctp_obs@STATION_I@…: not a simple integer: '0.00000')

The the rrd file was not updating any more.I checked lots of those rrd files that only "COUNTER" type had this problem. "GAUGE" types were working fine and updated as usual.

Oh by the way , I am pretty sure I had sent the counter values as integer as it worked in RRDtool 1.3.9

make sure you use the latest version ... many bugs have been fixed. Report back if it still does not work. cheer tobi
