[rrd-users] rrdtool.OperationalError: reached EOF while loading header rrd->stat_head

[ikreb]

Hey,

i write in python and use the rrdtool version 1.4.7.

my script works for weeks and suddently i get this error message:
rrdtool.OperationalError: reached EOF while loading header rrd->stat_head

the error occurs in the function:
rrdtool.update(file_name, 'string_with_arguments')

Any ideas? Or need you more information?

Looks like your rrd file has been corrupted and truncated; the RRD function
is trying to read the file header but hits end-of-file.

Either it is truncated to almost 0 length, or else the file can be opened
but not read (SELinux issues?), or you have another underlying filesystem
error. I suppose another possibility is that you're reading the wrong file
and it isn't an RRD at all.
