rrd files corrupted? RRDTool stuck ...

[julia]

Hi,

I'm using Cacti 0.8.5a with cactid on a Solaris machine. Since two weeks it keeps apearing that the same graphs are not being rendered. Sometines it is in the Graph-Debug view, in the toal view or in the detailed view. Some processes of the RRDTool are stuck on the machine and grep as much CPU as they can. So I could only kill those processes.

The only ting that helps is deleting the old graphs/datasources and make new graphs. But after some days the same thing keeps appearing again with the same graphs.

This seems to happen only to graphs with the same graph templates. But not to all graphs made with this templates are effected. Is this a known error and is there a possible solution?

Thanks in advance,
Julia.
